    Description / Table of Contents: On 2-(Dimethylaminomethyl)ferrocenyl Compounds of Vanadium, Niobium, and TantalumFormer results, indicating the ability of (dimethylaminomethyl)ferrocenyl groups forming stable σ-organo transition-metal derivatives, were proved by the synthesis of heterobimetallic 2-(dimethylaminomethyl)ferrocenyl compounds of the three-valued vanadium as well as five valued niobium and tantalum from VCl3, NbCl5, TaCl5, and (FcN)Li (I).The synthesis and properties of the compounds (FcN)2VCl (II), (FcN)nNbCl5-n(THF)x [n = 1, x = 1,3 (III); n = 2, x = 0 (IV); n = 3, x = 0 (V)] as well as (FcN)TaCl4(THF)1.5 (VI) are reported. An intensive characterization, especially in respect of possible chelate structures was tried by i.r., 1H-n.m.r., uv-vis, mass spectroscopy, and elementary analysis.
    Notes: Frühere Befunde, wonach (Dimethylaminomethyl)-ferrocenyl-Gruppen (FcN) zur Bildung stabiler σ-Organoübergangsmetall-Derivate befähigt sind, wurden durch die Synthese heterobimetallischer 2-(Dimethylaminomethyl)-ferrocenyl-Verbindungen des dreiwertigen Vanadiums sowie des fünfwertigen Niobs und Tantals aus den Metallchloriden VCl3, MCl5 (M = Nb, Ta) und (FcN)Li (I) bestätigt. Die Darstellung und die Eigenschaften der Verbindungen (FcN)2VCl (II), (FcN)nNbCl5-n(THF)x [n = 1, x = 1,3 (III); n = 2, x = 0 (IV); n = 3, x = 0 (V)] sowie von (FcN)TaCl4 · 1,5 THF (VI) werden mitgeteilt. Eine eingehende Charakterisierung, insbesondere hinsichtlich der Ausbildung möglicher Chelatstrukturen, erfolgte durch IR-, 1H-NMR-, UV-VIS- und Massenspektroskopie sowie durch Elementaranalysen.

    Description / Table of Contents: Contributions to the Chemistry of Transition Metal Alkyl Compounds. 58 On 2-(Dimethylaminomethyl)ferrocenyl Compounds of Vanadium, Molybdenum, Tungsten, Thorium, and UraniumEarlier results according to which dimethylaminomethylferrocenyl groups (FcN) are able to form stable organometallic chelate compounds were confirmed by synthesis of the heterobimetallic chelate compounds (FcN)2VO · Li(acac) II, (FcN)MoO2(acac) III, (FcN)WOCl3 IV, (FcN)Th(acac)3 V, and (FcN)UO2(acac) VI from the corresponding metal acetylacetonates or oxidchlorides and (FcN)Li I. The new compounds were characterized by elemental analysis, the i.r., 1H-n.m.r., and electron spectra and by their effective magnetic moments.

    Description / Table of Contents: Contributions to Organolanthanide Chemistry. II. On 2-(dimethylaminomethyl)ferrocenyl Compounds of Yttrium, Dysprosium, and HolmiumEarly reports about the ability of the 2-(dimethylaminomethy1)ferrocenyl group to form stable heterobimetallic organolanthanide(III) compounds have been confirmed by the synthesis of the organolanthanide(III) derivatives (C5H5)2Ln(FcN) [Ln = Y (II), Dy (III), Ho (IV)], C5H5Dy(FcN)2 · 2,5 THF (V) und C5H5Ln(FcN)Cl [Ln = Dy (VI), Ho (VII)] from the corresponding cyclopentadienyllanthanide(III) chlorides (C5H5)2LnCl or C5H5LnCl2 resp. and (FcN)Li (I). The products have been characterized by elemental analyses, IR-, 1H-NMR, 13C-NMR and UV/Vis spectra as well as mass spectra and the determination of their effective magnetic moments.
