Beiträge zur Chemie der Alkylverbindungen von Übergangsmetallen. XVIII. Darstellung und Eigenschaften von Vanadintetrabenzyl und von Benzyltantalchloriden

Contributions to the Chemistry of Transition Metal Alkyl Compounds. XVIII. On the Preparation and Properties of Tetrabenzyl Vanadium and Benzyl Tantalum Chlorides Pure 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.
