    Notes: Homoleptic intramolecularly stabilized organozinc, -cadmium, and -mercury compounds MR2, with R bearing an amino function, have been synthesized from the corresponding metal dichlorides MCl2 and the lithium salts LiC6H4CH2NEt2-2 (1), LiC6H3(CH2NMe2)2-2,6 (2), LiC6H3(CH2NEt2)2-2,6 (3), (LiCH2CH2CH2)2NMe (4), and LiCH2CH2CH2NC5H10 (5). The crystal structures of Hg(C6H4CH2NEt2-2)2 (1c), [M(CH2CH2CH2)2NMe]2 [M = Zn (4a), Hg (4c)], and of M(CH2CH2CH2NC5H10)2 [M = Zn (5a), Cd (5b)] have been determined by X-ray diffraction. 4a and 4c form dimers with an unusual coordination number (three) of the central metal.

    Notes: The solid-state structures of the four homodinuclear chelate complexes, [Na2(Y2OHEC)(H2O)2] · 7 H2O · C2H5OH (1), [Na2(Gd2OHEC)(H2O)2] · 12 H2O (2), [Na2(Eu2OHEC)(H2O)2] · 11 H2O (3), and [Cs2(La2OHEC)(H2O)2] · 14 H2O (4) (H8OHEC = 1,4,7,10,14,17,20,23-octaazacyclohexacosane-1,4,7,10,14,17,20,23-octaacetic acid), were determined by X-ray crystal structure analysis. Each lanthanide(III) ion is ninefold coordinated by eight donor atoms of the ligand system and the oxygen atom of one water molecule. The structures are compared with those of DOTA- and TETA-coordinated complexes and the conformation of the OHEC ligand system with that of the parent amine and its dinuclear copper complex. NMR investigations of the diamagnetic complex 1indicate a very similar environment of the lanthanide cations in solution and in the solid state. Low-temperature and variable-temperature 1H-NMR measurements prove the existence of two isomers of 1 (3.5:1 ratio) which undergo conformational processes. The rate constants of these processes were deduced from a complete line shape analysis and were used to determine the activation parameters.Supporting information for this article is available on the WWW under http://www.wiley-vch.de/contents/jc_2005/1999/99081_s.pdf or from the author.

    Spaltungsreaktionen metallorganischer Verbindungen mit Chalkogenen. Reaktionen von Schwefel mit silicium-, germanium- und bleiorganischen Verbindungen (1963)

    Description / Table of Contents: The reaction of the metal organic compounds PbR4, GeR4, GeR4 and SiR4 (R = C4H9 and C6H5) with elementary sulphur has been studied. Under the choosen conditions, the lead compounds seem to decompose in a radical mechanism. The other compounds react similar to the corresponding tin compounds which had been studied earlier by us: Sulphur-sulphur bonds undergo a stepwise nucleophilic cleavage by carbanions which are splitt of from the starting materials under the influence of polar sulphur chains.Reactions temperature and the nature of the isolated degradation products (because of a different thermal stability of possible intermediates) are naturally depending on the polar character of the metal-carbon bonds in the starting materials.
    Notes: Die Metallorganyle PbR4, GeR4 und SiR4 (R = C4H9- und C6H5-) werden bei höheren Temperaturen mit elementarem Schwefel umgesetzt. Während die Bleiverbindungen unter den gewählten Bedingungen offensichtlich radikalisch zerfallen, reagieren die leichteren Homologen in Analogie zu den früher von uns untersuchten Zinnverbindungen unter Abspaltung von Carbanionen (unter dem Einfluß polarer Schwefelketten), die dann Schwefel—Schwefel-Bindungen nucleophil spalten. Die Reaktionstemperatur solcher Umsetzungen und damit die Natur der gefundenen Abbauprodukte (wegen der unterschiedlichen thermischen Beständigkeit möglicher Zwischenprodukte) hängt erwartungsgemäß von der Polarität der Me—C-Bindungen der Ausgangsstoffe ab.

    Description / Table of Contents: Far below its temperature of decomposition tetraphenyltin reacts with the elements of the Vth, and IIIrd. main group of the periodic table (except nitrogen). In the case of phosphorus, besides triphenylphosphine, tinorganic intermediates may be isolated, whereas with arsenic and antimony only the triphenyl-compounds can be prepared. They are easily available by this method. With Bismuth as well as with all the elements of the IIIrd. main group under the prevailing conditions the phenyl-compounds are thermally not stable. Biphenyl and the corresponding tin-alloys are isolated as decomposition products.
    Notes: Zinntetraphenyl reagiert mit den Elementen der V. und III. Hauptgruppe (außer Stickstoff) weit unterhalb seiner Zersetzungstemperatur. Während beim Phosphor neben Triphenylphosphin noch zinnorganische Zwischenprodukte des Abbaues isolierbar sind, können bei Arsen und Antimon nur noch die Triphenylverbindungen gefaßt werden, die so präparativ leicht zugänglich wurden. Diese Phenylverbindungen sind im Falle von Wismut und allen Elementen der III. Hauptgruppe thermisch so unbeständig, daß nur ihre Zerfallsprodukte Biphenyl und die entsprechende Zinnlegierung isolierbar sind.
