    Zeitschrift für die chemische Industrie 76 (1964), S. 249-258 
    Details
    ISSN: 0044-8249
    Keywords: Chemistry ; General Chemistry

    Topics: Chemistry and Pharmacology
    Notes: In dieser Arbeit werden verbesserte Wege zur Darstellung von 19-nor-Steroiden beschrieben. Sie beruhen auf neuen Totalsynthesen des Östrons und auf der intramolekularen Funktionalisierung und Eliminierung der Methylgruppe C-19 in Androstan-Derivaten.

    Übergangsmetallpolysulfide, Koordinationsverbindungen mit rein anorganischen Chelatliganden (1985)
    Weinheim : Wiley-Blackwell
    Zeitschrift für die chemische Industrie 97 (1985), S. 745-760

    Topics: Chemistry and Pharmacology
    Notes: Es ist schon sehr lange bekannt, daß sich manche Übergangsmetallsulfide in wäßrigem Ammoniumpolysulfid lösen. Obwohl anzunehmen war, daß sich dabei Metallpolysulfide bilden, hat man sich diesem Verbindungstyp erst in den letzten Jahren intensiver zugewandt. Dabei konnte eine Fülle neuer Komplexe mit Polysulfido-Chelatliganden Sn2- (n=2,3,4…) isoliert und charakterisiert werden. Die Komplexe interessieren bezüglich ihrer Struktur und Reaktivität, aber auch im Hinblick auf mögliche Anwendungen; mit ihnen können Schwefelringe definierter Größe gezielt hergestellt werden, und es deutet sich an, daß sie auch in der Katalyse Verwendung finden könnten.

    Notes: This review describes approaches for improved preparations of 19-norsteroids. They are based on novel total syntheses of estrone and on intramolecular functionalization and elimination of the C-19 methyl group in androstane derivatives.

    Transition Metal Polysulfides: Coordination Compounds with Purely Inorganic Chelate Ligands (1985)
    Weinheim : Wiley-Blackwell
    Angewandte Chemie International Edition in English 24 (1985), S. 742-757

    ISSN: 0570-0833
    Keywords: Polysulfides ; Transition metals ; Chelates ; Sulfides ; Chemistry ; General Chemistry

    Topics: Chemistry and Pharmacology
    Notes: It has been long known that certain transition metal sulfides dissolve in aqueous ammonium polysulfide. Although it was assumed that they thereby formed metal polysulfides, attention was first paid to such compounds only a few years ago. In recent years a host of new complexes with polysulfido chelate ligands have been isolated and characterized. The complexes are of interest not only regarding their structure and reactivity but also in view of their potential uses; they can be used for the directed preparation of sulfur rings of a given size, and there are indications that they will find applications in catalysis.

    Radial and latitudinal gradients in the interplanetary magnetic field - Evidence for meridional flux transport (1986)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: Magnetic field data obtained by the Pioneer 10 and 11 spacecraft in the heliosphere from 1972-1982 and earth orbiting satellite data are examined in terms of radial and latitudinal gradients in the field components and magnitude. The data reveal that higher than expected gradients are observed in the magnetic field and time variations affect the field throughout the low-latitude heliosphere. It is determined that the high radial gradient is caused by meridional flux transport with low-latitude field lines moving to higher heliographic latitudes. High pressure near the solar equator and pressure due to heating in compressive solar wind interaction regions and the large field magnitudes that occur in these regions are investigated as mechanisms that produce the meridional flux. A solar cycle variation in the level of flux transport is analyzed.

    Theoretical interpretation of the observed interplanetary magnetic field radial variation in the outer solar system (1985)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: Observations of the azimuthal component of the IMF are evaluated through the use of an MHD model which shows the effect of magnetic flux tubes opening in the outer solar system. It is demonstrated that the inferred meridional transport of magnetic flux is consistent with predictions by the MHD model. The computed azimuthal and radial magnetic flux deficits are almost identical to the observations. It is suggested that the simplest interpretation of the observations is that meridional flows are created by a direct body force on the plasma. This is consistent with the analytic model of Nerney and Suess (1975), in which such flux deficits in the IMF arise naturally from the meridional gradient in the spiralling field.

    A white dwarf companion to the main-sequence star 4 Omicron(1) Orionis and the binary hypothesis for the origin of peculiar red giants (1988)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Ultraviolet spectra of the peculiar red giants (PRGs) called MS stars are investigated, and the discovery of a white dwarf (WD) companion to the MS star 4 Omicron(1) Orionis is reported. The observations and data analysis are discussed and compared with those for field WDs in order to derive parameters for the WD and the luminosity of the primary. Detection limits for the other MS stars investigated are derived, and the binary hypothesis for PRGs is reviewed.
