    Geflüchtete in ländlichen Regionen Deutschlands (2022)
    Springer Nature | Springer Fachmedien Wiesbaden
    Details
    Publication Date: 2022-11-19
    Description: Die Open-Access-Publikation präsentiert umfangreiche empirische Analysen zu Halte- und Bleibeorientierung Geflüchteter und richtet den Blick dabei besonders auf die Situation der ländlichen Regionen Deutschlands. Migrations- und Integrationsforschung in Deutschland war bislang überwiegend auf Großstädte ausgerichtet. Durch den vermehrten Zuzug geflüchteter Menschen seit 2014 sehen sich jedoch auch Kleinstädte und Dörfer in ländlichen Regionen verstärkt mit Aufgaben der Aufnahme und Integration von Geflüchteten konfrontiert. Ziel dieses Buches ist es, empirisch fundiert zu beantworten, unter welchen Voraussetzungen und wie humanitäres Engagement und ländliche Entwicklung erfolgreich verbunden werden können und wie dies von Politik und Zivilgesellschaft positiv beeinflusst werden kann.

    Im Spannungsverhältnis zwischen Selbst- und Fremdverstehen (2023)
    Springer Nature | Springer Fachmedien Wiesbaden

    Publication Date: 2024-03-29
    Description: Dieser Open-Access-Sammelband hinterfragt, wie sich internationale Kulturzusammenarbeit zwischen Ländern unterschiedlicher Kultursysteme und -traditionen erreichen lässt. In Deutschland ist Auswärtige Kulturpolitik von dem Gedanken geleitet, dass globale Herausforderungen Multilateralismus erfordern. Im chinesischen Diskurs dagegen finden andere Kernbegriffe wie z.B. „Tianxia“ Verwendung, die im nicht-chinesischen Kontext einer Interpretation bedürfen. Um der Differenz – aber auch den Gemeinsamkeiten – auf den Grund zu gehen, untersuchen Wissenschaftler*innen und Praktiker*innen aus China und Deutschland Selbst- und Fremdwahrnehmungen sowie Kooperationen in kulturellen Begegnungen. Auf diese Weise sollen Grundlagen für ein besseres gegenseitiges Verständnis sowie für kulturelle Kooperation zwischen beiden Ländern ermöglicht werden.

    A novel oxygen induced reduction of α, β-unsaturated carbonyl compounds by benzeneselenol (1988)

    Notes: A novel oxygen induced reduction of α,β-unsaturated carbonyl compounds is discovered. The reduction of the carbon-carbon double bond of α,β-unsaturated carbonyl compounds by benzeneselenol was caused by an introduction of molecular oxygen into the reaction system. This reduction is likely to proceed via a radical chain pathway involving an SH2 type reaction between a phenylseleno radical and a 1,2-adduct of benzeneselenol to the carbonyl group of the α,β-unsaturated carbonyl compound to give an allylic radical which absracts a hydrogen atom from benzeneselenol to form the reduction product.

    Notes: The photochemical reaction of MAQO with various aromatic amines were studied by ESR. The results show that nitroxide radicals are stable productrs of the photooxidation of both diphenylamines and phenylamines. The photolyzed phenothiazine does not yield nitroxide as the final product, instead it gives the neutral radical as the stable final product.

    Relative rates of bromination and chlorination of 4-substituted cyclopentenes in methanol, ethanol and acetic acid (1989)

    Notes: A set of 4-monosubstituted cyclopentenes, , were synthesized and their relative rates (kX/kH) for bromination and chlorination were determined in methanol, ethanol and acetic acid at 25 °C by competitive method. log(kX/kH) for most of the substituents can be correlated by means of Taft's equation, log(kX/kH) = ρI σI + C. In methanol ρI, Br2 = -2·91, ρI, Cl2 = -0·49, in ethanol ρI, Br2 = -3·07, ρI, Cl2 = -0·70 and in acetic acid ρI, Br2 = -1·64, ρI, Cl2 = -0·65. The presence of C(〈0) is due to a constant steric effect. The deviation of X = H is ascribed to the absence of the steric effect and that of X = CO2Me and CO2Et is accounted for in terms of anchimeric assistance. For chlorination no anchimeric assistance was observed.

    The cation radical vinylcyclobutane rearrangement (1989)
    Chichester : Wiley-Blackwell

    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Physics
    Notes: The cation radical vinylcyclobutane (VCB) rearrangement is found to be a reaction of substantial scope, synthetic utility, and exceptional kinetic facility. In conjuction with cation radical cyclobutanation, it constitutes an effective method for net (indirect) Diels-Alder addition to electron rich dienophiles. Reactions can be carried out with either aminium salt or photosensitized electron transfer (PET) initiation and are powerfully facilitated by ionizable substituents such as p-anisyl, phenylthio, and phenoxy at the 2-position of the vinylcyclobutane. The intramolecularity of the reaction is clearly established and in four discrete systems preferred sr (suprafacial/retention) stereochemistry is observed. A theoretical basis for sr stereochemistry in the cation radical VCB rearrangement is advanced. The transition state for the reaction is considered to be similar to that for the direct cation radical Diels-Alder cycloaddition, another cation radical pericyclic reaction which converges on the same product. This model of the VCB rearrangement transition state is used to rationalize the strong rate-retarding effect of a Z-methyl substituent attached to the vinyl group and of a methyl substituent at the 4-position of the vinylcyclobutane ring cis to the vinyl substituent.

    Syntheses, spectroscopic characterization and electronic structure of cyclopropenylidene ligated platinum complexes (1988)

    Notes: New series of platinum complexes of cyclopropenylidenes of the types of PtX2(CP)2 and trans-PtX(PBu3)2(CP) have been synthesized, where CP is di-t-butylcyclopropenylidene (BCP) or bis(diisopropylamino)cyclopropenylidene (ACP). The 13C-NMR chemical shifts, and 13C-195Pt coupling constants (1JPtC) for the complexes are discussed in comparison with those values derived from closely related series of compounds, trans-PtCl(PR3)2L; L — —CH3, —C6H5 and —C≡CBu-t. An excellent linear relationship through the origin was obtained between 1JPtC and the formal ‘s’ % character of the carbon directly bonded to Pt for the series trans-PtCl(PR3)2L in which the Pt—C bond is regarded as a pure σ-linkage, whereas 1JPtC deviates largely from this relationship when pπ—dπ bonding interaction possibly exists in the Pt—C bond. The NMR data suggest the strong nmr trans-influence of the cyclopropenylidenes and that in the Pt—CP bond the σ-interaction is appreciable but the π-interaction is negligible.

    The ‘dimer mechanism’ in aromatic nucleophilic substitution by amines in aprotic solvents (1989)

    Notes: The mechanism of aromatic nucleophilic substitutions by amines in protic solvents is well established; on the contrary the mechanism/s of the reactions in aprotic solvents is/are still subject of controversy. The present paper describes several systems for which fourth-order kinetics (third-order in amine) were observed. A mechanism is proposed to account for this as well as other observation such as: overall negative energies of activation, quadratic dependence of kA with non-nucleophilic tertiary bases, spectacular effects of hydrogen-bond donor (HBD) and hydrogen-bond acceptor (HBA) catalysts, etc. Other alternative mechanisms are also discussed.

    Notes: The kinetics and mechanisms of the reactions between 1-phenylethyl benzenesulfonates (1-PEB) with N,N-dimethylanilines are investigated in methanol at 35·0°C. Reactivity and selectivity trends were found to be similar to those for the reactions of 1-PEB with anilines, but the magnitudes of cross interaction constants, ρXZ, between substituents X in the nucleophile and Z in the leaving group were substantially smaller indicating no hydrogen-bond bypass bridge formation in the transition state. However, the magnitude of ρXZ suggested a direct electrostatic interaction between the reaction centers in the nucleophile and leaving group in the frontside nucleophilic attack with a loose transition state structure.
