    Description / Table of Contents: Contributions to the Chemistry of Transition Metal Alkyl Compounds. XX. On the Reaction of NiCl2 · 2 PR3 and CoCl2 · 2 PR3 with LiSn(CH2C6H5)3LiSn(CH2C6H5)3 reacts with NiCl2 · 2 P(n-C4H9)3 in tetrahydrofuran forming benzyl nickel chloride, which could be isolated in form of the bipyridyl complex C6H5CH2-NiCl · dipy. NiCl2 · 2 P(C6H5)3 and CoCl2 · 2 P(C6H5)3 are reduced to complexes of the formula MCl · 2 P(C6H5)3 · 3 THF (M = Ni, Co).
    Notes: LiSn(CH2C6H5)3 reagiert mit NiCl2 · 2 P(n-C4H9)3 in Tetrahydrofuran zu Benzylnickelchlorid, das als Dipyridylkomplex isoliert werden konnte. Bei Einsatz von NiCl2 · 2 P(C6H5)3 und CoCl2 · 2 P(C6H5)3 erfolgt dagegen eine Reduktion zu Komplexen der Zusammensetzung MCl · 2 P(C6H5)3 · 3 THF (M = Ni, Co).

    Description / Table of Contents: Contributions to the Chemistry of Transition Metal Alkyl Compounds. XXIX. Dibenzyl Manganese - Preparation and ReactionsManganese(II) acetylacetonate reacts with tribenzyl aluminium and dibenzyl magnesium forming the yellow complexes 3(C6H5CH2)2Mn · Al(acac)3 and (C6H5CH2)2Mn · Mg(acac)2 Dibenzyl manganese is also formed at the reaction of dibenzyl magnesium or benzyl magnesium chloride with MnCl2 · 1.5 THF and was separated as the dioxan complex (C6H5CH2)2Mn · 2C4H8O2, the ligands of which can be removed to a great extent in vacuum.Dibenzyl manganese reacts with CO2, CS2 and SO2 with insertion into the Mn-C-bonds. The corresponding manganese compounds were isolated and furtherly characterized.
    Notes: Mangan(II)-acetylacetonat reagiert mit Tribenzylaluminium bzw. Dibenzylmagnesium zu den gelben Komplexen 3(C6H5CH2)2Mn · Al(acac)3 bzw. (C6H5CH2)2Mn Mg(acac)2. Dibenzylmangan entsteht auch bei Einwirkung von Dibenzylmagnesium oder Benzyl magnesiumchlorid auf MnCl2 · 1,5 THF; eine Abtrennung von den Magnesiumsalzen gelingt in Form des 1,4-Dioxankomplexes (C6H5CH2)2Mn · 2C4H8O2, dessen Ligandenmoleküle im Vakuum weit gehend entfernt werden können.Dibenzylmangan reagiert mit CO2, CS2 und SO2 unter Insertion in die Mn-C-Bindungen. Die entsprechenden Mangansalze wurden isoliert und näher charakterisiert.

    Description / Table of Contents: Contributions to the Chemistry of Transition Metal Alkyl Compounds. XVIII. On the Preparation and Properties of Tetrabenzyl Vanadium and Benzyl Tantalum ChloridesPure tetrabenzyl vanadium was isolated and characterized by elementary analyses, EPR and 1H-NMR spectra, by hydrolysis and thermal decomposition.  -  Experiments for the preparation of tetra or pentabenzyl compounds of niobium and tantalum failed, but we could prepare C6H5CH2TaCl4, (C6H5CH2)2TaCl3, and (C6H5CH2)3TaCl2, the last two in form of bipyridyl complexes.
    Notes: Vanadintetrabenzyl wurde in definierter Form isoliert und durch Elementaranalyse, ESR- und 1H-NMR-Spektrum sowie durch die hydrolytische und thermische Spaltung charakterisiert.  -  Versuche zur Gewinnung von Tetra- und Pentabenzylverbindungen des Niobs und Tantals blieben erfolglos. Es gelang jedoch, die Verbindungen C6H5CH2—TaCl4, (C6H5CH2)2TaCl3 und (C6H5CH2)3TaCl2, zum Teil in Form von Dipyridylkomplexen, zu gewinnen.
