Darstellung und Eigenschaften der ferf-ButyHminovanadin(V)-Verbindungen tC4H9N =VX3 (X = Cl, RCOO) / Synthesis and Properties of Jerf -Butylimino vanadium (V) Compounds tC4H9N = VX3 (X = Cl, RCOO)

Abstract

¹C₄H₉N = V(OSiMe₃)₃ has been prepared by reaction of NH₄VO₃ with HNSiMe₃(^tC₄H₉). This compound is the starting material for the synthesis of C₆H₅N = V(OSiMe₃)₃ and ^tG₄H₉N = VCl₃ by transamination with aniline or redistribution with VOCl₃, respectively. The properties of the trichloride are studied by chemical reactions such as redistribution, complex formation and substitution with silver carboxylates. All compounds are mono-meric in solution, probably containing a nitrogen vanadium triple bond. The structure of 2,2'-dipyridyl complexes [^tC₄H₉N = VX₃ · C₁₀H₈N₂] (X = Cl, CH₃COO) has been found to be octahedral with meridional arrangement of chloride or acetate ligands.
