Abstract

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.
