    Description / Table of Contents: Contributions to the Chemistry of Organo Transition Metal Compounds. 53. Synthesis and Properties of Manganese Tetravinyloxide, Mn(OCH=CH2)4 · 0.5 THFTetrakis(1-Norbornyl)manganese (I) reacts with boiling tetrahydrofuran forming ethylene, norbornane, and manganese tetravinyloxide Mn(OCH=CH2)4 · 0.5 THF (II) as the first manganese tetraalcoxide. The compound was characterized by elementary analysis, the i.r. and 1H n.m.r. spectrum, the effective magnetic moment, and the protolysis products.
    Notes: Tetrakis(1-norbornyl)mangan (I) reagiert mit siedendem Tetrahydrofuran unter Abspaltung von Ethylen und Norbornan zu Mangantetravinyloxid, Mn(OCH=CH2)4 · 0,5 THF (II), als dem ersten bekannt gewordenen Mangan(IV)-alkoxid. Die Verbindung wurde durch Elementaranalyse, das IR- und 1H-NMR-Spektrum, das effektive magnetische Moment und durch die Protolyseprodukte charakterisiert.

    Description / Table of Contents: Contributions to the Chemistry of Transition Metal Alkyl Compounds. XXX. Synthesis and Characterization of Nitrobenzyl Nickel Compounds(C2H5)2Ni · dipy reacts with benzyl chlorides forming complexes of the type RNiCl · dipy. In this way nitro groups containing thermally stable organonickel compounds can be obtained, which cannot be achieved by means of organolithiiim or Grignard reagents. - In a similar way (C2H5)Ni · dipy reacts with to form · dipy.The composition of the compounds achieved was proved by analysis, by characteristic reactions, magnetic moments, and in part by their IR and M spectra.

    Description / Table of Contents: Contributions to the Chemistry of Organo Transition Metal Compounds. 52. Preparation, Characterization, and Reactions of (C5H5)3Ce · THF and Na[Ce(C5H5)4] · THF(C5H5)3 · THF (I) was synthesized in a simple manner by reaction of (NH4)2[Ce(NO3)6] with C5H5Na. With excess C5H5Na the complex Na[Ce(C5H5)4] · THF (II) could be obtained.In addition of cyclovoltammetric and polarographic measurements it was tried without success to transfer I and II into organocerium(IV) compounds by means of different oxidizing agents. II reacts with I2 and (C6H5)3CCl forming Na[(C5H5)3CeI] · THF or Na[(C5H5)2CeI2] · 4 THF and I besides of (C6H5)3CCl respectively. At interaction of I with Co(acac)3 the cobalticinium salt [(C5H5)2Co][C5H5Ce(acac)3] is formed.The compounds obtained were characterized by elementary analysis, hydrolysis products, magnetic moments, i.r., 1H-n.m.r. und u.v.-vis spectra, and measurements of electric conductivity.
    Notes: (C5H5)3 · THF (I) kann auf bequeme Weise durch Umsetzung von (NH4)2[Ce(NO3)6] mit C5H5Na erhalten werden. Bei Verwendung eines Überschusses von C5H5Na entsteht das bisher nicht beschriebene Na[Ce(C5H5)4] · THF (II).Ausgehend von cyclovoltammetrischen und polarographischen Messungen wurden Versuche zur Überführung von I und II in Organocer(IV)-Verbindungen mittels verschiedener Oxydationsmittel angestellt. Diese verliefen negativ im Sinne der Zielstellung. II reagiert mit I2 zu Na[(C5H5)3CeI] · THF bzw. Na[(C5H5)2CeI2]. 4 THF und mit (C6H5)3CCl zu (C5H5)3Ce · THF neben C5H5C(C6H5)3. Bei der Einwirkung von Co(acac)3 auf I entsteht das Cobalticinium-Salz [(C5H5)2Co][C5H5Ce(acac)3].Eine detaillierte Charakterisierung der erhaltenen Verbindungen erfolgte durch ihre Elementaranalysen, Hydrolysenprodukte, magnetischen Momente, IR-, 1H-NMR- und Elektronenspektren sowie durch Leitfähigkeitsmessungen.
