    Exploring Resilience (2021)
    Springer Nature
    Details
    Publication Date: 2021-02-10
    Description: Resilience has become an important topic on the safety research agenda and in organizational practice. Most empirical work on resilience has been descriptive, identifying characteristics of work and organizing activity which allow organizations to cope with unexpected situations. Fewer studies have developed testable models and theories that can be used to support interventions aiming to increase resilience and improve safety. In addition, the absent integration of different system levels from individuals, teams, organizations, regulatory bodies, and policy level in theory and practice imply that mechanisms through which resilience is linked across complex systems are not yet well understood. Scientific efforts have been made to develop constructs and models that present relationships; however, these cannot be characterized as sufficient for theory building. There is a need for taking a broader look at resilience practices as a foundation for developing a theoretical framework that can help improve safety in complex systems. This book does not advocate for one definition or one field of research when talking about resilience; it does not assume that the use of resilience concepts is necessarily positive for safety. We encourage a broad approach, seeking inspiration across different scientific and practical domains for the purpose of further developing resilience at a theoretical and an operational level of relevance for different high-risk industries. The aim of the book is twofold: 1. To explore different approaches for operationalization of resilience across scientific disciplines and system levels. 2. To create a theoretical foundation for a resilience framework across scientific disciplines and system levels. By presenting chapters from leading international authors representing different research disciplines and practical fields we develop suggestions and inspiration for the research community and practitioners in high-risk industries. This book is Open Access under a CC-BY licence. ; Explores different approaches for operationalization of resilience across scientific disciplines and system levels Creates a theoretical foundation for a resilience framework across scientific disciplines and system levels Develops suggestions and inspiration for the research community and practitioners in high-risk industries Presents chapters from leading international authors representing different research disciplines and practical fields

    City of the Future Graduation Lab (2023)
    TU Delft OPEN Publishing
    Details
    Publication Date: 2024-03-23
    Description: The Cross Domain City of the Future Graduation Lab, situated in the Faculty of Architecture and the Built Environment at TU Delft, has been a pioneer in experimenting with a multidisciplinary approach to education on the built environment. Drawing upon this expertise over the past years, this book reflects on multidisciplinarity in the built environment and its implementation in education on the built environment. How should one approach multidisciplinarity in education and practice? What encompasses its core elements, benefits, and challenges? By addressing these questions, the book aims to inform students and practitioners within the realm of the built environment by sharing insights from experiences in multidisciplinary education. It presents eight conclusions regarding the future of multidisciplinary education and, thereby, seeks to contribute to a more humane and sustainable future for cities: 1.Process is central to multidisciplinary collaboration. Negotiating positions, ensuring an environment of respect, balance and open-mindedness, and setting a common vocabulary. 2.Multidisciplinarity can be a way to foster innovation. It triggers complementarity and confrontation. As with any innovation, there is potential for greater outcomes, but, at the same time, extra risks emerge. These need to be managed. 3.Multidisciplinarity could be better integrated into organisational structures. 4.Disciplinarity and multidisciplinarity are in mutual coexistence. They are inseparable. They can complement and contradict each other. 5.Problem precedes solution, not the opposite. Framing the problem, or ‘problematizing’, is a considerable share of the actual solution. This is particularly applicable to multidisciplinarity. 6.Multidisciplinarity is by nature composed of fluid boundaries. Navigating through an enormous diversity of perspectives requires agility, flexibility, independence, spirit of adventure and embracing uncertainty. 7.Professionals should be trained as ‘T-shape’: grounded in their field while able to dialogue with other fields. 8.Both generalists and specialists are needed. Education should provide opportunities for both.

    Handbook of Contact Mechanics (2021)
    Springer Nature
    Details
    Publication Date: 2024-04-07
    Description: This open access book contains a structured collection of the complete solutions of all essential axisymmetric contact problems. Based on a systematic distinction regarding the type of contact, the regime of friction and the contact geometry, a multitude of technically relevant contact problems from mechanical engineering, the automotive industry and medical engineering are discussed. In addition to contact problems between isotropic elastic and viscoelastic media, contact problems between transversal-isotropic elastic materials and functionally graded materials are addressed, too. The optimization of the latter is a focus of current research especially in the fields of actuator technology and biomechanics. The book takes into account adhesive effects which allow access to contact-mechanical questions about micro- and nano-electromechanical systems. Solutions of the contact problems include both the relationships between the macroscopic force, displacement and contact length, as well as the stress and displacement fields at the surface and, if appropriate, within the half-space medium. Solutions are always obtained with the simplest available method - usually with the method of dimensionality reduction (MDR) or approaches which use the solution of the non-adhesive normal contact problem to solve the respective contact problem.

    BioMEMS (2021)
    Taylor & Francis | CRC Press
    Details
    Publication Date: 2022-04-28
    Description: As technological advancements widen the scope of applications for biomicroelectromechanical systems (BioMEMS or biomicrosystems), the field continues to have an impact on many aspects of life science operations and functionalities. Because BioMEMS research and development require the input of experts who use different technical languages and come from varying disciplines and backgrounds, scientists and students can avoid potential difficulties in communication and understanding only if they possess a skill set and understanding that enables them to work at the interface of engineering and biosciences. Keeping this duality in mind throughout, BioMEMS: Science and Engineering Perspectives supports and expedites the multidisciplinary learning involved in the development of biomicrosystems. Divided into nine chapters, it starts with a balanced introduction of biological, engineering, application, and commercialization aspects of the field. With a focus on molecules of biological interest, the book explores the building blocks of cells and viruses, as well as molecules that form the self-assembled monolayers (SAMs), linkers, and hydrogels used for making different surfaces biocompatible through functionalization. The book also discusses: Different materials and platforms used to develop biomicrosystems Various biological entities and pathogens (in ascending order of complexity) The multidisciplinary aspects of engineering bioactive surfaces Engineering perspectives, including methods of manufacturing bioactive surfaces and devices Microfluidics modeling and experimentation Device level implementation of BioMEMS concepts for different applications. Because BioMEMS is an application-driven field, the book also highlights the concepts of lab-on-a-chip (LOC) and micro total analysis system (μTAS), along with their pertinence to the emerging point-of-care (POC) and point-of-need (PON) applications.

    Electricity in Africa (2023)
    Boydell & Brewer | James Currey an imprint of Boydell & Brewer
    Details
    Publication Date: 2024-03-29
    Description: No country has managed to develop beyond a subsistence economy without ensuring at least minimum access to electricity for the majority of its population. Yet many sub-Saharan African countries struggle to meet demand. Why is this, and what can be done to reduce energy poverty and further Africa's development? Examining the politics and processes surrounding electricity infrastructure, provision and reform, the author provides an overview of historical andcontemporary debates about access in the sub-continent, and explores the shifting role and influence of national governments and of multilateral agencies in energy reform decisions. He describes a challenging political environment for electricity supply, with African governments becoming increasingly frustrated with the rules and the processes of multilateral donors. Civil society also began to question reform choices, and governments in turn looked to new development partners, such as China, to chart a fresh path of energy transformation. Drawing on over fifteen years of research on Uganda, which has one of the lowest levels of access to electricity in Africa and has struggled to construct several, large hydroelectric dams on the Nile, Gore argues that there is a critical need to recognize how the changing political and social context in African countries, and globally, has affected the capacity to fulfil national energy goals, minimize energy poverty and transform economies.

    Safety Cultures, Safety Models (2021)
    Springer Nature
    Details
    Publication Date: 2024-04-16
    Description: The objective of this book is to help at-risk organizations to decipher the “safety cloud”, and to position themselves in terms of operational decisions and improvement strategies in safety, considering the path already travelled, their context, objectives and constraints. What link can be established between safety culture and safety models in order to increase safety within companies carrying out dangerous activities? First, while the term “safety culture” is widely shared among the academic and industrial world, it leads to various interpretations and therefore different positioning when it comes to assess, improve or change it. Many safety theories, concepts, and models coexist today, being more or less appealing and/or directly useful to the industry. How, and based on which criteria, to choose from the available options? These are some of the questions addressed in this book, which benefits from the expertise of its worldwide famous authors in several industrial sectors.

    Details
    Publication Date: 2024-04-04
    Description: An investigation of how-to guides for sensor technologies Sensors are increasingly common within citizen-sensing and DIY projects, but these devices often require the use of a how-to guide. From online instructional videos for troubleshooting sensor installations to handbooks for using and abusing the Internet of Things, the how-to genres and formats of digital instruction continue to expand and develop. As the how-to proliferates, and instructions unfold through multiple aspects of technoscientific practices, Jennifer Gabrys asks why the how-to has become one of the prevailing genres of the digital. How to Do Things with Sensors explores the ways in which things are made do-able with and through sensors and further considers how worlds are made sense-able and actionable through the instructional mode of citizen-sensing projects. Forerunners: Ideas First Short books of thought-in-process scholarship, where intense analysis, questioning, and speculation take the lead

    Oil Fictions (2023)
    Pennsylvania State University Press
    Details
    Publication Date: 2024-03-27
    Description: Oil, like other fossil fuels, permeates every aspect of human existence. Yet it has been largely ignored by cultural critics, especially in the context of the Global South. Seeking to make visible not only the pervasiveness of oil in society and culture but also its power, Oil Fictions stages a critical intervention that aligns with the broader goals of the energy humanities.Exploring literature and film about petroleum as a genre of world literature, Oil Fictions focuses on the ubiquity of oil as well as the cultural response to petroleum in postcolonial states. The chapters engage with African, South American, South Asian, Iranian, and transnational petrofictions and cover topics such as the relationship of colonialism to the fossil fuel economy, issues of gender in the Thermocene epoch, and discussions of migration, precarious labor, and the petro-diaspora. This unique exploration includes testimonies of the oil encounter—through memoirs, journals, and interviews—from a diverse geopolitical grid, ranging from the Permian Basin to the Persian Gulf.By engaging with non-Western literary responses to petroleum in a concentrated, sustained way, this pathbreaking book illuminates the transnational dimensions of the discourse on oil. It will appeal to scholars and students working in literature and science studies, energy humanities, ecocriticism, petrocriticism, environmental humanities, and Anthropocene studies.In addition to the editors, the contributors to this volume include Henry Obi Ajumeze, Rebecca Babcock, Ashley Dawson, Sharae Deckard, Scott DeVries, Kristen Figgins, Amitav Ghosh, Corbin Hiday, Helen Kapstein, Micheal Angelo Rumore, Simon Ryle, Sheena Stief, Imre Szeman, Maya Vinai, and Wendy W.

    Publication Date: 2024-04-04
    Description: Sensors are everywhere. Small, flexible, economical, and computationally powerful, they operate ubiquitously in environments. They compile massive amounts of data, including information about air, water, and climate. Never before has such a volume of environmental data been so broadly collected or so widely available. Grappling with the consequences of wiring our world, Program Earth examines how sensor technologies are programming our environments. As Jennifer Gabrys points out, sensors do not merely record information about an environment. Rather, they generate new environments and environmental relations. At the same time, they give a voice to the entities they monitor: to animals, plants, people, and inanimate objects. This book looks at the ways in which sensors converge with environments to map ecological processes, to track the migration of animals, to check pollutants, to facilitate citizen participation, and to program infrastructure. Through discussing particular instances where sensors are deployed for environmental study and citizen engagement across three areas of environmental sensing, from wild sensing to pollution sensing and urban sensing, Program Earth asks how sensor technologies specifically contribute to new environmental conditions. What are the implications for wiring up environments? How do sensor applications not only program environments, but also program the sorts of citizens and collectives we might become? Program Earth suggests that the sensor-based monitoring of Earth offers the prospect of making new environments not simply as an extension of the human but rather as new "technogeographies" that connect technology, nature, and people.

    Stoßprobleme in Physik, Technik und Medizin (2021)
    Springer Nature
    Details
    Publication Date: 2024-04-04
    Description: Dieses Open Access Buch widmet sich dem Problem der Mechanik des Zusammenstoßes zweier makroskopischer Körper. Falls die Dynamik der Körper als Ganzes dies erlaubt, ohne in unüberschaubare Komplexität zu verfallen (in der Regel ist das nur für das reine Normalstoßproblem der Fall), werden allgemeine axialsymmetrische Stoßpartner betrachtet. Für das allgemeine räumliche Stoßproblem wird sich auf den Kontakt von Kugeln beschränkt. Zunächst werden im Buch sehr ausführlich die kontaktmechanischen Grundlagen (Elastizität, Plastizität, Viskoelastizität, Adhäsion, Gradientenmedien) dargestellt und anschließend auf das Stoßproblem übertragen. Mit der Methode der Dimensionsreduktion, der ein eigenes Kapitel gewidmet ist, steht außerdem seit wenigen Jahren ein Werkzeug zu Verfügung, das die sehr effiziente analytische und numerische Behandlung von dynamischen Kontaktproblemen (wie z.B. Stößen) ermöglicht. Den Abschluss des Buch bilden Anwendungsfälle aus verschiedenen Gebieten.

    Model Tests and Numerical Simulations of Liquefaction and Lateral Spreading (2021)
    Springer Nature
    Details
    Publication Date: 2021-02-10
    Description: This open access book presents work collected through the Liquefaction Experiments and Analysis Projects (LEAP) in 2017. It addresses the repeatability, variability, and sensitivity of lateral spreading observed in twenty-four centrifuge model tests on mildly sloping liquefiable sand. The centrifuge tests were conducted at nine different centrifuge facilities around the world. For the first time, a sufficient number of experiments were conducted to enable assessment of variability of centrifuge test results. The experimental data provided a unique basis for assessing the capabilities of twelve different simulation platforms for numerical simulation of soil liquefaction. The results of the experiments and the numerical simulations are presented and discussed in papers submitted by the project participants. The work presented in this book was followed by LEAP-Asia that included assessment of a generalized scaling law and culminated in a workshop in Osaka, Japan in March 2019. LEAP-2020, ongoing at the time of printing, is addressing the validation of soil-structure interaction analyses of retaining walls involving a liquefiable soil. A workshop is planned at RPI, USA in 2020.

    Open Design Systems (2023)
    TU Delft OPEN Publishing
    Details
    Publication Date: 2024-03-29
    Description: Current systems design and decision management methodologies can be single-sided, ignoring or failing to capture the dynamic interplay between multi-stakeholder preferences (‘what they want’) and system performances (‘what they can’). In addition, these methodologies often contain fundamental modelling errors and do not provide single best-fit solutions. This leaves designers or decision-makers without unique answers to their problems. Above all, mainstream higher education primarily applies instructivist and research-based learning methods, and therefore does not adequately prepare students for designing solutions to future complex problems. This book introduces both a state-of-the-art participatory design methodology (Odesys), and a design-based learning concept (ODL), which together overcome the aforementioned issues. Odesys is a pure act of open design integration to confront conflicting socio-technical interests and is the key to unlocking these complexities to deliver socially responsible systems. Odesys’ design engine, the Preferendus, enables stakeholders to cooperatively identify their best-fit design synthesis. It employs a novel optimisation method that maximises the aggregated preferences, integrating sound mathematical and extended U-modelling via open technical-, social-, and purpose cycles. The art of ODL is a constructivist design-based and well-proven learning concept fostering students’ design capabilities to become open and persistent problem solvers. It is a reflective, creative, and engaged learning approach that opens human development and unlocks new knowledge and solutions. The author also introduces new management features such as the corporate social identifier (CSI), the ‘socio-eco’ threefold organization model and U-model based open loop management. Finally, the author places Odesys & ODL within the integrative context of empiricism, rationalism, spiritualism, and constructivism to unite the open design impulse. This book will be of interest to both academics and practitioners working in the field of complex systems design and managerial decision-making, and functions as a textbook on systems design and management for master students from diverse backgrounds.

    Gender and STEM: Understanding Segregation in Science, Technology, Engineering and Mathematics (2021)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2023-12-20
    Description: This volume features thirteen original chapters on the causes and consequences of gender segregation in scientific, technical, engineering, and mathematics (“STEM”) occupations and fields of study. Although women have made great strides in equalizing access to labor markets and higher education, many STEM fields—particularly in the physical sciences and engineering—remain strongholds of gender segregation in the United States and other reputably gender-progressive societies. Policymakers, business leaders and activists have launched countless initiatives to diversify access to lucrative, high status occupations and ameliorate labor shortages that diminish innovation and competitiveness. Contributors to this volume apply diverse theoretical lenses and methodological approaches to understand the individual, interactional, organizational, and cultural dynamics that drive this segregation in the United States. Results show that the gender composition of scientific and technical fields varies a great deal over time and across organizational contexts and socio-demographic groups defined by race, ethnicity, class, and sexuality. But despite this variability, STEM work and STEM workers are widely presumed to be naturally and inevitably masculine. Research presented here reveals how these stereotypes combine with cultural beliefs about natural and fundamental differences between men and women to produce gendered aspirations and reinforce inequalities in the US scientific and technical workforce.

    Publication Date: 2024-03-24
    Description: Uncanny computer-generated animations of splashing waves, billowing smoke clouds, and characters’ flowing hair have become a ubiquitous presence on screens of all types since the 1980s. This Open Access book charts the history of these digital moving images and the software tools that make them. Unpredictable Visual Effects uncovers an institutional and industrial history that saw media industries conducting more private R&D as Cold War federal funding began to wane in the late 1980s. In this context studios and media software companies took concepts used for studying and managing unpredictable systems like markets, weather, and fluids and turned them into tools for animation. Unpredictable Visual Effects theorizes how these animations are part of a paradigm of control evident across society, while at the same time exploring what they can teach us about the relationship between making and knowing.

It addresses sources of frustration in senior management with high expectations of operational recommendations and disquiet on the part of HOF specialists struggling to have an impact on high-level decision making. The brief explores these issues with an emphasis on examples and lessons learned based on the experience of its authors, who come from different academic disciplines and various industrial sectors such as oil and gas, energy and transportation. It then offers some ways forward for a better consideration of HOF in hazardous companies with a view of promoting safety and facing challenges in a rapidly changing world.

    Description: Dieses Buch ist eine Open-Access-Publikation unter einer CC BY 4.0 Lizenz. Künstliche Intelligenz (KI) klingt in aktuellen Debatten oft abstrakt und alltagsfremd. Doch die meisten Internetnutzerinnern und -nutzer sind bereits täglich mit ihr konfrontiert – wenn auch unbewusst: sei es bei der Sprachsteuerung des Smartphones, bei Kaufempfehlungen im Online-Shop oder bei der Abfrage von auf Webseiten häufig gestellten Fragen (Frequently Asked Questions, FAQ). KI ist ein Teilaspekt der Digitalisierung, der als Schlagwort immer häufiger in den Medien auftaucht. Das aktuell große Interesse liegt darin begründet, dass es in den vergangenen Jahren verschiedene technologische Fortschritte gab, welche die Nutzung der KI nun auf andere Ebenen heben. Mit diesem Themenband des Instituts für Innovation und Technik (iit) „Künstliche Intelligenz“ erhalten Leserinnen und Leser einen schlaglichtartigen Einblick in die KI hinsichtlich ihrer Technologien, aktuellen und potenziellen Anwendungen sowie Auswirkungen auf die Gesellschaft.

    Description: It is common for us today to associate the practice of science primarily with the act of seeing—with staring at computer screens, analyzing graphs, and presenting images. We may notice that physicians use stethoscopes to listen for disease, that biologists tune into sound recordings to understand birds, or that engineers have created Geiger tellers warning us for radiation through sound. But in the sciences overall, we think, seeing is believing. This open access book explains why, indeed, listening for knowledge plays an ambiguous, if fascinating, role in the sciences. For what purposes have scientists, engineers and physicians listened to the objects of their interest? How did they listen exactly? And why has listening often been contested as a legitimate form of access to scientific knowledge? This concise monograph combines historical and ethnographic evidence about the practices of listening on shop floors, in laboratories, field stations, hospitals, and conference halls, between the 1920s and today. It shows how scientists have used sonic skills—skills required for making, recording, storing, retrieving, and listening to sound—in ensembles: sets of instruments and techniques for particular situations of knowledge making. Yet rather than pleading for the emancipation of hearing at the expense of seeing, this essay investigates when, how, and under which conditions the ear has contributed to science dynamics, either in tandem with or without the eye.

    Risk Communication for the Future (2021)
    Springer Nature
    Details
    Publication Date: 2024-03-25
    Description: The conventional approach to risk communication, based on a centralized and controlled model, has led to blatant failures in the management of recent safety related events. In parallel, several cases have proved that actors not thought of as risk governance or safety management contributors may play a positive role regarding safety. Building on these two observations and bridging the gap between risk communication and safety practices leads to a new, more societal perspective on risk communication, that allows for smart risk governance and safety management. This book is Open Access under a CC-BY licence.

    Ambisonics (2021)
    Springer Nature
    Details
    Publication Date: 2024-04-07
    Description: This open access book provides a concise explanation of the fundamentals and background of the surround sound recording and playback technology Ambisonics. It equips readers with the psychoacoustical, signal processing, acoustical, and mathematical knowledge needed to understand the inner workings of modern processing utilities, special equipment for recording, manipulation, and reproduction in the higher-order Ambisonic format. The book comes with various practical examples based on free software tools and open scientific data for reproducible research. The book’s introductory section offers a perspective on Ambisonics spanning from the origins of coincident recordings in the 1930s to the Ambisonic concepts of the 1970s, as well as classical ways of applying Ambisonics in first-order coincident sound scene recording and reproduction that have been practiced since the 1980s. As, from time to time, the underlying mathematics become quite involved, but should be comprehensive without sacrificing readability, the book includes an extensive mathematical appendix. The book offers readers a deeper understanding of Ambisonic technologies, and will especially benefit scientists, audio-system and audio-recording engineers. In the advanced sections of the book, fundamentals and modern techniques as higher-order Ambisonic decoding, 3D audio effects, and higher-order recording are explained. Those techniques are shown to be suitable to supply audience areas ranging from studio-sized to hundreds of listeners, or headphone-based playback, regardless whether it is live, interactive, or studio-produced 3D audio material.

    Poor Man's Fortune (2023)

    Publication Date: 2024-04-02
    Description: White working-class conservatives have played a decisive role in American history, particularly in their opposition to social justice movements, radical critiques of capitalism, and government help for the poor and sick. While this pattern is largely seen as a post-1960s development, Poor Man's Fortune tells a different story, excavating the long history of white working-class conservatism in the century from the Civil War to World War II. With a close study of metal miners in the Tri-State district of Kansas, Missouri, and Oklahoma, Jarod Roll reveals why successive generations of white, native-born men willingly and repeatedly opposed labor unions and government-led health and safety reforms, even during the New Deal. With painstaking research, Roll shows how the miners' choices reflected a deep-seated, durable belief that hard-working American white men could prosper under capitalism, and exposes the grim costs of this view for these men and their communities, for organized labor, and for political movements seeking a more just and secure society. Roll's story shows how American inequalities are in part the result of a white working-class conservative tradition driven by grassroots assertions of racial, gendered, and national privilege.

    Quantification of bone surface textures: exploring a new method of ontogenetic ageing (2023)
    In:  Journal of Analytical Science and Technology vol. 14 no. 1
    Details
    Publication Date: 2024-02-26
    Description: Identifcation of ontogenetic age classes plays an important role in the felds of zoology, palaeontology and archaeology, where accurate age classifcations of (sub)fossil remains are a crucial component for the reconstruction \nof past life. Textural ageing\xe2\x80\x94the identifcation of age-related bone surface textures\xe2\x80\x94provides a size-independent \nmethod for age assessment of vertebrate material. However, most of the work so far is limited to qualitative results. \nWhile qualitative approaches provide helpful insights on textural ageing patterns, they are heavily subject to observer \nbias and fall short of quantitative data relevant for detailed statistical analyses and cross-comparisons. Here, we present a pilot study on the application of 3D surface digital microscopy to quantify bone surface textures on the long \nbones of the grey heron (Ardea cinerea) and the Canada goose (Branta canadensis) using internationally verifed \nroughness parameters. Using a standardised measuring protocol, computed roughness values show a strong correlation with qualitative descriptions of textural patterns. Overall, higher roughness values correspond to increased numbers of grooves and pits and vice versa. Most of the roughness parameters allowed distinguishing between diferent \nontogenetic classes and closely followed the typical sigmoidal animal growth curve. Our results show that bone \ntexture quantifcation is a feasible approach to identifying ontogenetic age classes.

    Description / Table of Contents: Chemistry of NariciclasineFrom narciclasine (2a), the acetonide 8a and its oxidation product 10 are prepared. 10 isomerizes easily to give 11. Catalytic hydrogenation of 2a yields a mixture of dihydronarci-clasines from which the pure cis- and trans-isomers 14a and 15a can be obtained via the tetraacetates. As a by-product of the hydrogenation, isonarciclasine (16a) is isolated. The relative configuration of narciclasine (as represented by formula 2a) is established by the n. m. r. spectra of 15b and 16b. Lycoricidine and margetine are shown to be identical; their configuration is as shown in formula 2b. Some biological tests are reported.
    Notes: Aus Narciclasin (2a) wird das Acetonid 8a und dessen Oxidationsprodukt 10 dargestellt. 10 wird leicht zu 11 isomerisiert. Das bei der katalytischen Hydrierung von 2a anfallende Gemisch der Dihydronarciclasine wird über die Tetraacetate in die cis- und trans-Verbindungen 14a und 15a aufgetrennt. Als Nebenprodukt der katalytischen Hydrierung entsteht Isonarciclasin (16a). Mit Hilfe der NMR-Spektren von 15b und 16b läßt sich die relative Konfiguration des Narciclasins entsprechend 2a beweisen. Lycoricidin und Margetin sind identisch und haben die Konfiguration 2b. Über einige biologische Teste wird berichtet.

The furan- (5a) and pyrrole derivatives 7a and b give the tetraethyl difuro- (6) and dipyrrolo[3, 4-b: 3′, 4′-g]tetroxecin- 1, 3, 7, 9-tetracarboxylates 8a and b, respectively.
    Notes: Es wird über Methylenierungsversuche an 3,4-Dihydroxy- Verbindungen der Thiophen-Furan-, 1-Phenyl- und 1- (Äthoxycarbonylmethyl)-2,5-pyrroldicarbonsäure- diäthylester berichtet. Die Methylenierungen führen nur beim 3,4-Dihydroxy-2,5-thiophendicarbonsäure-diäthylester (1) zu den 3,4-Methylendioxythiophen-Derivaten 2 und 3, wobei als Nebenprodukt der Dithieno[3,4-b: 3′,4′-g]tetroxecin-1,3,7,0-tetracarbonsäure- tetraäthylester (4) gebildet wird. Bei dem Furan- (5a) und den Pyrrol-Derivaten 7a und b entstehen die Difuro- (6) bzw. die Dipyrrolo[3,4- b: 3′,4′-g]tetroxecin-1,3,7,9- tetracarbonsäure-tetraäthylester 8a, b.

    Description / Table of Contents: On the Photochemistry of AlleneAcetophenone-sensitized irradiation of allene yields a complex mixture of products, from which the allene dimer 1, the trimers 2 and 3, and the ketones 4 and 5 have been isolated. This is in contrast to the reported thermal di- and trimerization of allene, which lead to products such as 1, 8-12. The planar allene triplet 13, derived by way of a nonvertical triplet-triplet energy transfer, presumably plays a key role in the photosensitized oligomerization of allene. Also, the formation of the ketone 5 is easily explained in terms of an attack of 13, through its central C-atom to the o-position of the acetophenone, to give 16, which cyclizes ultimately to yield 5. At 240°C, 5 undergoes fragmentation to the starting materials. The α,β-unsaturated ketone 4 arises through a [2 + 2]-photocycloaddition reaction of the 3(n,π*) state of acetophenone to methylacetylene via the oxetene intermediate 6, followed by ring-opening.
    Notes: Die acetophenon-sensibilisierte Belichtung von Allen liefert eine komplexe Produktmischung, aus der sich das Allendimere 1, die Trimeren 2 und 3 sowie die Ketone 4 und 5 isolieren lassen. Dieser Befund steht im Gegensatz zur beschriebenen thermischen Di- und Trimerisierung des Allens, die zu 1, 8-12 führt. Eine Schlüsselrolle bei der photosensibilisierten Allen-Oligomerisierung spielt vermutlich das durch nichtvertikale Triplett-Triplett-Energieübertragung gebildete planare Allen-Triplett 13. Auch die Entstehung des Bicyclo[4.2.0]octadien-Ketons 5 erklärt sich zwanglos durch einen Angriff von 13 mit seinem mittleren C-Atom in der o-Position des Acetophenons unter Bildung der Zwischenstufe 16, die Ringschluß zu 5 erfährt. Bei 240°C erleidet 5 Rückspaltung in die Ausgangskomponenten. Das α,β-ungesättigte Keton 4 ist dagegen Ergebnis einer [2 + 2]-Photocycloaddition des Acetophenons im 3(n,π*)-Zustand an Methylacetylen zum Oxeten 6 mit anschließender Ringöffnung.

    Description / Table of Contents: Organosulfur Compound, XI. Synthesis of 13-3-Oxathiol-spirofuranones and Furanone-spirodihydrothiopyrans from 4-Thioxotetrahydrofuran-3-onesHeterocyclic, non-enolisable α-oxo-thioketones of furan-type 9 have been prepared for the first time. These highly unstable compounds undergo dimerisation and subsequent elimination of sulfur to give 1,3-oxathiol-spirofuranones 11. In competition with this process reaction with the eliminated active sulfur can occur to yield a dispiro-1,2,4-trithiolan 10a. In the presence of dimethylbutadiene the new α-oxo-thioxofurans 9 react according to the Diels-Alder principle to form the furanone-spirodihydrothiopyrans 13. The reaction mechanisms are discussed.
    Notes: Es werden erstmals heterocyclische, nicht enolisierbare α-Oxo-thioketone vom Furantyp (9) hergestellt, die außerordentlich instabil sind und unter Dimerisierung mit anschließender Schwefeleliminierung reagieren, wobei die bisher unbekannten 1,3-Oxathiol-spirofuranone 11 entstehen. In Konkurrenz hierzu kann Reaktion mit dem bei der Fragmentierung gebildeten aktiven Schwefel unter Bildung eines Dispiro-1,2,4-trithiolans (10a) eintreten. In Gegenwart von Dimethylbutadien reagieren die neuen α-Oxo-thioxo-furane 9 ausschließlich nach dem Diels-Alder-Prinzip unter Bildung der Furanon-spirodihydrothiopyrane 13. Die Reaktions-mechanismen werden diskutiert.

Bis(VIA metal)methylstibines-Preparation, Quaternization and OxidationCH3SbBr2 reacts with the transition metal anions of Na[Fe(CO)2π-C5H5] and Na[M(CO)3π-C5H5] (M=Cr, Mo, W) to give CH3Sb[Fe(CO)2π-C5H5]2 and CH3Sb[M(CO)3π-C5H5]2 (M=Cr, Mo, W). via stepwise metalation. Starting with the primary substitution products BrCH3Sb—M(CO)3π-C5H5 (M=Mo, W) the heteronuclear species π-C5H5(CO)3Cr—Sb-(CH3)—M(CO)3π-C5H5 (M=Mo, W) and π-C5H5(CO)3Mo—Sb(CH3)—W(CO)3π-C5H5 can be obtained. Reactions with alkyl halides result in the quaternization of the Sb-atom or the cleavage of the Sb—M bond. In the first case metal substituted Sb-cations of the type [{π-C5H5(CO)3M}2Sb(CH3)R]⊕ (M=Mo, W; R=CH3, C2H5, C6H5CH2) are formed, which can also be synthesized by reaction of monometalated stibines with metal halides [{e. g. π-C5H5(CO)3Mo—Sb(CH3)2 and π-C5H5(CO)3MoBr]. Bromine adds on VB element, to yield transition metal derivatives with presumable pentacoordinated antimony ([π-C5H5(CO)3W]2SbCH3Br2). The chemical and spectroscopic properties of the new antimony transition metal complexes are reported.
    Notes: Die Umsetzung von CH3SbBr2 mit den Übergangsmetall-Anionen von Na[Fe(CO)2π-C5H5] und Na[M(CO)3π-C5H5] (M=Cr, Mo, W) führt unter stufenweiser Metallierung zur Bildung von CH3Sb[Fe(CO)2π-C5H5]2 und CH3Sb[M(CO)3π-C5H5]2 (M=Cr, Mo, W). Ausgehend von den primären Substitutionsprodukten BrCH3Sb—M(CO)3π-C5H5 (M=Mo, W) Können die heteronuclearen Spezies π-C5H5(CO)Cr—Sb(CH3)—M(CO)3π-C5H5 (M=Mo, W) und π-C5H5(CO)3Mo—Sb(CH3)—W(CO)3π-C5H5 erhalten werden. Reaktionen mit Alkylhalo-geniden verlaufen unter Quartärisierung am Sb-Atom oder Spaltung der Sb—M-Einheit. Im ersten Fall werden metallsubstituierte Sb-Kationen der Form [{π-C5H5(CO)3M}2Sb(CH3)R]⊕; (M=Mo, W; R=CH3, C2H5, C6H5CH2) gebildet, die auch aus monometalliertem Stibin und komplexem Metallhalogenid zugänglich sind [z. B. π-C5H5(CO)3MoSb(CH3)2 und π-C5H5(CO)3MoBr]. Die Einwirkung von Brom verläuft unter Addition am VB-Element und liefert Übergangsmetallderivate mit vermutlich pentakoordiniertem Antimon([π-C5H5(CO)3W]2sbCH3Br2). Die chemischen und spektroskopischen Eigenschaften der neuen Antimon-Übergangsmetallkomplexe werden beschrieben.

    Description / Table of Contents: Hydrogenolysis of Small Cycloalkanes, II. hydrogenation Basketane- and Snoutane-Derivativescis- and both trans-dimethyl twistane-4,5-dicarboxylates (9 and 11, 13) are formed via the dihydro intermediates 4-7 by hydrogenation of cis- and trans-dimethyl basketane-9,10-dicarboxylates (1 and 3) over Pd/C under normal conditions. During the uptake of the first mole-equivalent of hydrogen all the basketane derivatives were rearranged to snoutane derivatives (22 and 24) to some extent. The second C—C bond is cleaved on that side of the basketane skeleton, which is opposite to the first hydrogenated one. cis- and trans-dimethyl snoutane-9,10-dicarboxylates (22 and 24) were hydrogenated under the same conditions but more slowly via the dihydro derivatives (25, 27 and 29, 31) to yield cis- and trans-dimethyl isotwistanedicarboxylates (33 and 35). In snoutane derivatives the second cyclopropane ring is cleaved exclusively from the same side of the molecule as the first one. This is shown by separate hydrogenations of dihydro snoutane derivatives (27, 37 and 38). Hydrogenation of basketene (21) provides a mixture containing 70-75% of twistane (17) and 25-30% of isotwistane (39). The reasons for the different ways of hydrogenation in both systems are discussed. The configurations of all dihydro intermediates and endproducts have been established.
    Notes: cis- und trans-Basketan-9,10-dicarbonsäure-dimethylester (1 und 3) werden unter Normal-bedingungen mit Pd/C in Methanol über die isomeren Dihydrozwischenstufen (4-7) zu cis- und den beiden trans-Twistan-4,5-dicarbonsäure-dimethylestern (9 und 11, 13) hydriert. Bei der Hydrogenolyse der ersten C—C-Bindung erfolgt teilweise Umlagerung zu Snoutanderivaten (22 und 24). Die Öffnung der zweiten Bindung am Basketangerüst geschieht ausschließlich an der zur ersten hydrierten Bindung gegenüberliegenden Molekülseite. cis- und trans-Snoutan-9,10-dicarbonsäure-dimethylester (22 und 24) reagieren unter den gleichen Bedingungen ebenfalls, aber langsamer, über die Zwischenstufen (25, 27 und 29, 31) zu cis- und trans-Isotwistan-dicarbonsäure-dimethylester (33 und 35). An den getrennt untersuchten Zwischenstufen 27, 37 und 38 wird gezeigt, daß im Snoutangerüst beide Cyclopropanringe ausschließlich von der gleichen Molekülseite angegriffen werden. Aus Basketen (21) erhält man bei der Hydrierung ein Gemisch von 70-75% Twistan (17) und 25-30% Isotwistan (39). Die Ursachen für den verschiedenen Hydrierungsverlauf in beiden Systemen werden erörtert, und die Konfiguration aller Zwischenstufen und Endprodukte wird aufgeklärt.

    Description / Table of Contents: Aromatic Diazonium, VI; Nitrosoacylamines and Diazoesters, XIV A New Reaction Mode of N-NitrosoacetanilideA side reaction in the decomposition on N-nitrosoacetanilide in ethanol/potassium acetate, which has been described to produce a salt K[C8H8N3O3]6), was reinvestigated. It is probale that this compound is formed by a free radical addition of NO to the nitroso group of N-nitrosoacetanilide and subsequent reduction. The potassium salt and the corresponding silver salt are considered to be derived from N-nitroso-N-(N-phenylacetamido)hydroxylamine (7) in agreement with spectroscopic data. Dynamic n. m. r. allows to measure a rotation process with ΔG≠ = 16.0 and ΔG° = 0.6 kcal/mole.
    Notes: Eine früher beschriebene6) Nebenreaktion beim Zerfall des N-Nitrosoacetanilids in Äthanol/Kaliumacetat, die zur Bildung eines Salzes K[C8H8N3O3] führte, wurde erneut untersucht. Es ist wahrscheinlich, daß diese Verbindung durch radikalische Addition von NO an die Nitrosogruppe des N-Nitrosoacetanilids und anschließende Reduktion entsteht. Das Kaliumsalz und ein entsprechendes Silbersalz werden in Übereinstimmung mit spektroskopischen Daten als Salze des N-Nitroso-N-(N-phenylacetamido)hydroxylamins (7) formuliert. Die NMR-Linienformanalyse gestattet die Messung einer Rotationsschwelle mit ΔG≠ = 16.0 und ΔG° = 0.6 kcal/ mol.

    Description / Table of Contents: Reactions with Derivatives of the (CH)8CH2-Family; the Governing Influence of Substituents on the Photolysis of Several cis3a,7a-DihydroindenesOn photochemical or thermal activation the tricyclo[4.3.0.02,5]nonadienes 10, 12, 14a, b, 16 are transformed to the cis-dihydroindenes 11, 13, 15a, b, 17. As determined by the reaction halflives at 120 and 153°C, respectively, the thermal stability of the starting compounds decreases in the order 14b 〉 14a ⋍ 16 〉 12 〉 10; steric reasons are discussed as a possible explanation for this sequence. Cycloaddition reaction of 11, 13, 15a, b, (17 is unreactive) with maleic anhydride and 4-phenyl-1,2,4-triazoline-3,5-dione, respectively, yield the adducts 21(21′)a, b, 22a, b, 24 and 25 for which the endo-configuration of the carbocyclic five-membered ring with respect to the C-8/C-9 double bond is unambigously proven at least in the case of 22a, b by formation of the cagephotoproducts 23a, b. Irradiation of the dihydroindenes involves different pathways: while excitation of 13 leads back to the tricyclic diene 12 the tetraesters 15a, b are converted to the intramolecular cyclization products 28a, b, and the diphenyl-compound 17 undergoes phenyl migration affording the di-π-methane isomer 30; all reactions proceed in a specific manner and only under direct irradiation conditions.
    Notes: Die Tricyclo[4.3.0.02,5]nonadiene 10, 12, 14a, b, 16 wandeln sich bei photochemischer oder thermischer Aktivierung in die cis-Dihydroindene 11, 13, 15a, b, 17 um. Aus den bei 120 bzw. 153°C ermittelten Halbwertszeiten der Isomerisierungen ergibt sich für die Ausgangsverbindungen eine in der Reihenfolge 14b 〉 14a ⋍ 16 〉 12 〉 10 abnehmende thermische Stabilität; als Ursache hierfür werden sterische Faktoren diskutiert. Cycloadditonen von Maleinsäureanhydrid bzw. 4-Phenyl-1.2.4-triazolin-3.5-dion an 11, 13, 15a, b (17 reagiert nicht) liefern die Addukte 21(21′)a,b, 22a,b,24 und 25 für welche die endo-Anordnung des carbocyclischen Fünfrings bezüglich der C-8/C-9-Doppelbindung zumindest für 22,a b duch die photochemische Bildung der Käfigverbindungen 23a, b, gesichert ist. Ber der Belichtung der Dihydroindene ist das Ergebnis sehr unterschiedlich: während der Diester 13 den Tricyclus 12 zurückbildet, werden die Tetraester 15a, b in einer intramolekularen Cyclisierung zu 28a, b und das Diphenyl-Substrat 17 in einer Di-π-Methan-Umlagerung zu 30 umgewandelt; alle Reaktionen verlaufen spezifisch und nur unter direkten Bestrahlungsbedingungen.

    Description / Table of Contents: Reaction of N-Substituted Amidines with Heterocumulenes, V. Reactions with Isothiocyanates and IsocyanatesN1, N2-Dialkyl-substituted amidines (e.g. 1) react with methyl isothiocyanate at room temperature to give thiocarbamoylamidines (e. g. 6) without an intramolecular hydrogen bond, whereas at elevated temperatures cyclic 1: 2-adducts (30-32) are formed. Aromatic isothiocyanates yield exchange products (34-37), whereas cyclic amidines (15-17) yield thiocarbamoylamidines (20, 26, 27) with intramolecular NH…N-bridges because of lower steric hindrance around R2. - The reaction between N1, N2-dialkyl-substituted amidines and isocyanates in the presence of larger groups R2 or strongly electron-withdrawing groups R5 yields only instable carbamoylamidines. The zwitter-ion intermediate (4) then undergoes an intramolecular reaction to give exchange products or adds a dipolarophile to yield 1,3,5-triazacyclohexane derivatives (46, 47, 51-54). These products are not formed when attack on C-2 is rendered considerably more difficult by R2 (tert-C4H9) (43, 56) or when R2=CH3 favours the formation of a very strong hydrogen bond (55).
    Notes: N1, N2-Dialkylsubstituierte Amidine (z. B. 1) reagieren mit Methylisothiocyanat bei Raumtemperatur zu Thiocarbamoylamidinen ohne intramolekulare Wasserstoffbrücke (z. B. 6), bei höheren Temperaturen zu cyclischen 1:2-Addukten (30-32). Aromatische Isothiocyanate führen zu Austauschprodukten (34-37), cyclische Amidine (15-17) geben dagegen Thiocarbamoylamidine (20, 26, 27) mit intramolekularen NH…N-Brücken infolge sterischer Entlastung um R2.  -  Die Umsetzung N1, N2-dialkylsubstituierter Amidine mit Isocyanaten führt in Gegenwart größerer Reste R2 oder stark elektronenabziehender Substituenten R5 nur zu instabilen Carbamoylamidinen. Das intermediär entstehende Zwitterion (4) reagiert dann intramolekular zu Austauschprodukten oder unter Anlagerung eines Dipolarophils zu 1,3,5-Triazacyclohexanderivaten (46, 47, 51-54). Diese Produkte werden nicht gebildet, wenn R2 (tert-C4H9) den Angriff an C-2 beträchtlich erschwert (43, 56) oder R2=CH3 die Ausbildung einer besonders festen Wasserstoffbrücke begünstigt (55).

In solution the Z-isomers, (Z)-2-(1-acetoxyethylidene)-1-indanone (7B) and (Z)-2-(1-acetoxybenzylidene)-1-indanone (9aB) as well as 9bB and 9cB show a rapid equilibrium by acetyl group migration with the 2-acyl-3-indenyl acetates 7C and 9C:7B ⇄ 7C, 9B ⇄ 9C. The isomerisation of the semicyclic C=C double bond 7B ⇄ 7A or 9B ⇄ 9A is catalysed photochemically. The kinetic parameters of the acetyl group migration have been determined by n. m. r. line-shape analysis for the isomeric enol esters 2-benzoyl-3-indenyl acetate (9aC) and 3-benzoyl-2-indenyl acetate (10C).

    Description / Table of Contents: Reactions of Short-Life Radicals, XII. Free Radical Substitution at the Sulfur Atom: The Induced Degradation of (Thio)Carbonyl DisulfidesDibenzoyl, diacetyl, bis(thiobenzoyl) disulfide (1, 2, 7), and benzoyl 4-tolyl disulfide (11) are degradated by hydrides R3SnH at 60°C about 103 times faster than in the spontaneous degradation. The products and following reactions have been established. In all cases, SH2 mechanisms are found, with attack of stannyl radicals at the (acyl bound) sulfur atom. In the case of 1, 2 and 11, ΔHspont.≠ is 35 or 34 ± 2 kcal/mole at 150°C.
    Notes: Dibenzoyl-, Diacetyl-, Bis(thiobenzoyl)disulfid (1, 2, 7) und Benzoyl(4-tolyl)disulfid (11) werden durch Hydride R3SnH bei 60°C im Verhältnis zum Spontanzerfall etwa um den Faktor 103 rascher abgebaut. Produkte und Folgereaktionen werden sichergestellt. Es liegen jeweils SH2-Mechanismen mit Angriff von Stannyl-Radikalen am (acylseitigen) Schwefel vor. Bei 1, 2 und 11 ist ΔH spont.≠ = 35 bzw. 34 ± 2 kcal/mol bei 150°C.

    Description / Table of Contents: Crystal and Molecular Structure of Bis(triphenylphosphine)iminium Tetracarbonylpropyliron, [{(C6H5)3P}2 N] [Fe(Co)4C3H7]The crystal and molecular structure of the title compound has been determined by X-ray diffraction methods. The yellow salt crystallizes in the monoclinic space group C2/c with 8 molecules per cell. The structure was solved by conventional methods (agreement factor R1 = 0.07). Within the trigonal bipyramidal coordination polyhedron of the [Fe(CO)4C3H7] anion, the propyl group occupies an axial position. The bond length Fe-Cpropyl is 220(2) pm, the Fe-Cco distances are equal within experimental error (mean value 175(2) pm). The distances within the [{(C6H5)3P}2N] cation are similar to those found for the same ion in different crystalline salts. However, unexpectedly, an hitherto unknown new conformation is observed for the cation.
    Notes: Die Kristall- und Molekülstruktur der Titelverbindung wurde durch Röntgenbeugungsanalyse bestimmt. Das gelbe Salz kristallisiert in der monoklinen Raumgruppe C2/c mit 8 Molekülen in der Elementarzelle. Die Lösung der Struktur erfolgte mit konventionellen Methoden (Übereinstimmungsfaktor R1 = 0.07). Im [Fe(CO)4C3H7]-Anion besetzt die Propylgruppe eine axiale Position des trigonal-bipyramidalen Koordinationspolyeders um das Eisen. Die Fe-CPropyl-Bindungslänge beträgt 220(2) pm, die Fe-Cco-Abstände sind innerhalb der Fehlergrenzen gleich lang (Mittelwert: 175(2) pm). Die Abstände innerhalb des [{(C6H5)3P}2N]-Kations unterscheiden sich nicht von denen, die für das gleiche Ion in verschiedenen kristallinen Salzen gefunden wurden; unerwarteterweise liegt das Kation jedoch in einer neuen, bislang unbekannten Konformation vor.

    Description / Table of Contents: Reactions with Cyclobutenediones, XXXVII. Reactions of (2,5-Dimethoxyphenyl)phenyl-and Diphenylcyclobutenedione with Diazoalkanes. A Contribution to the Study of Isomerism of Possible 1-Pyrazolines(2,5-dimethoxyphenyl)phenylcyclobutenedione (7) reacts with diazomethane to give only 3a-(2,5-Dimethoxyphenyl)-4-methoxy-6-oxo-6a-phenyl-3,3a,6,6a-tetrahydrocyclopentapyrazole (8a). In glacial acetic acid 8a isomerizes to the 2-pyrazoline 9a. Diphenylcyclobutenedione (1) reacts with diazoethane to yield the diastereomeric 1-pyrazolines 10 and 11. These two compounds isomerize in glacial acetic acid to form the same 2-pyrazoline 12 and react with acetyl chloride to give the same N-acetyl derivative 13. In xylene 10 reacts to form the 4-ethoxy-3,6-dimethyl-1,5-diphenylbicyclo[3.1.0]hex-3-en-2-one (14), while in boiling tetrahydronaphthalene 10 gives two isomeric phenols 16 and 18.
    Notes: (2,5-Dimethoxyphenyl)phenylcyclobutendion (7) reagiert mit Diazomethan in Benzol ausschließlich zu 3a-(2,5-Dimethoxyphenyl)-4-methoxy-6-oxo-6a-phenyl-3,3a,6,6a-tetrahydrocyclopentapyrazol (8a). Dieses kann in Eisessig zum 2-Pyrazolin 9a umgelagert werden. Diphenylcyclobutendion (1) reagiert mit Diazoäthan zu zwei diastereomeren 1-Pyrazolinen 10 und 11. Beide ergeben in Eisessig das gleiche 2-Pyrazolin 12 sowie mit Acetylchlorid das N-Acetyl-Derivat 13. In Xylol wird 10 in das 4-Äthoxy-3,6-dimethyl-1,5-diphenylbicyclo[3.1.0]hex-3-en-2-on (14) und in Tetralin in die isomeren Phenole 16 und 18 übergeführt.

    Description / Table of Contents: Phosphazenes, LII. Redox Disproportionation of PCl3 and CH3PCl2 during the condensation with an Aminodi(phosphazene)In a condensation and concomitant redox disproportionation CH3PCl2 and PCl3 convert the NPNPN chain of bis(aminodiphenylphosphorus) nitride chloride 6 into six-membered rings. 2-Chloro-2-methylcyclotri(phosphazene) 12 and spirobi[cyclotri(phosphaza)]pentaene 8 (as hydrochloride 7, X = Cl) are obtained, respectively. An intermediate of the spirophosphazene formation is the chloro-hydrido-λ5- or the λ3-phosphazene 4, X = Cl, or 5, respectively. It is of importance, that the second rings starts to form before the spiro center is oxidized. Competing oxidation by CCl4 leads to the gem. dichlorophosphazene 13, which enters no further reaction.
    Notes: Unter gleichzeitiger Redoxdisproportionierung schließen CH3PCl2 und PCl3 die NPNPN-Kette von Bis(aminodiphenylphosphor)nitridchlorid 6 zum Sechsring. Es entsteht das 2-Chlor-2-methyl-cyclotri(Phosphazen) 12 bzw. das Spirobi[cyclotri(phosphaza)]pentaen 8 (als Hydrochlorid 7, X = Cl). Zwischenstufe der Spirophosphazen-Bildung ist das Chlor-hydrido-λ5-oder das λ3-Phosphazen 4, X = Cl, bzw. 5. Wesentlich ist, daß die Angliederung des zweiten Rings noch vor der Oxidation des Spirozentrums eingeleitet wird. Die konkurrierende Oxidation mit CCl4 führt zum gem. Dichlorphosphazen 13, das nicht mehr weiterreagiert.

    Description / Table of Contents: Hindered Ligand motion in Transition Metal Complexes, IV 13C N.M.R. Studies on Tricarbonyl-η6 -cyclopolyene complexes of the VIB ElementsThe 13C n.m.r. spectra of some tricarbonyl-n6-cyclopolyene complexes of the VIB elements with the cyclopolyenes 1,3,5-cycloheptatriene, 1,3,5-cyclooctatriene, and 1,3,5,7-cyclooctatetraene are reported. Two novel ligand movements have been detected in this group of half-sandwich complexes: 1. A hindered rotation of the cyclopolyene ligands around the prolonged threefold axis of the tricarbonylmetal groups with free energies of activation from 11.3 to 12.7 ± 0.3 kcal/mole. 2. The 1,3,5-cyclooctatriene ligand in C8H10Cr(CO)3 is frozen at - 120°C into a chiral conformation. The enantiomers can be interconverted over an energy barrier of 8.3 ± 0.1 kcal/mole.
    Notes: Die 13C-NMR-Spektren einiger Tricarbonyl-η6-cyclopolyen-Komplexe der Elemente der VI. Nebengruppe mit den cyclopolyenen 1,3,5-Cycloheptatrien, 1,3,5-Cyclooctatrien und 1,3,5,7-Cyclooctatetraen werden beschrieben. Zwei neuartige Ligandbewegungen konnten an dieser Gruppe von Halbsandwichkomplexen nachgewiesen werden: 1. Eine gehinderte Rotation der Cyclopolyenliganden um die verlängerte dreizählige Achse der Tricarbonylmetallgruppen mit freien Aktivierungsenthalpien von 11.3 bis 12.7 ± 0.3 kcal/mol. 2. Der.1,3,5-Cyclooctatrienligand in C8H10Cr(CO)3 ist bei - 120°C in einer chiralen Konformation eingefroren. Die beiden Enantiomeren können über eine Energiebarriere von 8.3 ± 0.1 kcal/mol ineinander übergeführt werden.

The Reaction of 2,3,3-Trimethylindolenines and 1-Methyl-3,4-dihydroisoquinoline with Acyliso(thio)cyanates5-Methoxy- and 5-nitro-2,3,3-trimethylindolenines (7a, b) react with dielectrophilic iso(thio)cyanates to give the pyrimido[3,4-a]indoles 14, 15. Furthermore, 7a affords a dicarbamoylmethylene derivative 16, which undergoes cyclization to the pyrimidinylidene indole 17. 1-Methyl-3,4-dihydroisoquinoline (21) condenses with dielectrophilic iso(thio)cyanates to the pyrimido[6,1-a]isoquino-lines 24, hitherto unknown in this stage of saturation.
