    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. XXIII. Phosphine Complexes of Benzyl Compounds of Nickel, Cobalt, and IronThe benzyl compound BzNi(acac) · PPh3 · 2 O(C2H5)2 could be obtained from Ni(acac)2, Bz3Al, and PPh3 in diethyl ether as a solvent. Using PBz3 and P(C6H11)3 complexes of the type BzNi(acac) · PR3 are formed. In a similar way Co(acac)3 and Fe(acac)3 react to BzCo(acac)2 · 2 PPh3, BzCo · 2 PPh3 · 2 O(C2H5)2 and BzFe · 3 PPh3 · 2 O(C2H5)2 (acacH = acetylacetone; Bz = C6H5CH2).
    Notes: Aus Ni(acac)2, Bz3Al und PPh3 konnte in Diäthyläther als Lösungsmittel die Benzylverbindung BzNi(acac) · PPh3 · 2 O(C2H5)2 gewonnen werden. Bei Verwendung von PBz3 und P(C6H11)3 entstehen Komplexe des Typs BzNi(acac) · PR3. Auf ähnliche Weise wurden aus Co(acac)3 und Fe(acac)3 die Komplexe BzCo(acac)2 · 2 PPh3, BzCo · 2 PPh3 · 2 O(C2H5)2 und BzFe · 3 PPh3 · 2 O(C2H5)2 erhalten (acacH = Acetylaceton; Bz = C6H5CH2).

    Description / Table of Contents: Contribution to the Chemistry of Transition Metal Alkyl Compounds. XXVIII. Benzylation of the Trivalent Titanium, Vanadium, and Chromium AcetylacetonatesBzCr(acac)2, 2Bz(Vacac)2 · Mg(acac)2 and 3BzV(acac)2 · Al(acac)3 were obtained in definite form by reaction of Cr(acac)3 and V(acac)3 with Bz3Al, Bz2Mg, and BzMgCl. Ti(acac)3, reacts with Bz2Mg and BzLi forming deep green Bz3Ti, which could'nt be isolated free of impurities (Bz = C6H5CH2, acacH = acetylacetone).
    Notes: Bei Reaktionen von Cr (acac)3 und V(acac)3 mit Bz3Al, Bz2Mg und BzMgCl wurden als definierte Verbindungen BzCr(acac)2, 2BzV(acac)2 · Mg(acac)2 und 3BzV(acac)2, Al(acac)3 erhalten. Aus Ti(acac)3 und Bz2Mg bzw. BzLi entsteht tiefgrünes Bz3Ti, das jedoch nicht frei von Verunreinigungen erhalten werden konnte. (Bz = C6H5CH2, acacH = Acetylaceton).

    Description / Table of Contents: Contributions to the Chemistry of Transition Metal Alkyl Compounds. XVI. On the Existence and Synthesis of Benzyl Nickel CompoundsIt is reported on experiments for benzylating nickel chloride and its triaryl and trialkylphosphine complexes by means of benzyl magnesium halides. Attempts for preparation of simple “binary” nickel benzyls failed, but it was possible to synthesize some o-substituted benzyl nickel compounds stabilized by trialkyl phosphines of the type
    Notes: Es wird über Versuche zur Benzylierung von Nickelchlorid und dessen Triaryl- und Trialkylphosphinkomplexen mittels Benzylmagnesiumhalogeniden berichtet. Während Versuche zur Gewinnung einfacher „binärer“ Nickelbenzyle fehlschlugen, gelang die Synthese einiger trialkylphosphinstabilisierter Benzylnickelderivate mit o-ständigen Substituenten in den Benzolringen vom Typ

    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.
