Syntheses of the homoleptic trimethylsilanolato complexes V(OSiMe3)3 and V(OSiMe3)4 are described. The thiovanadium(V)compound VS(OSiPh3)3 (11) is formed from [V(OSiPh3)3/s
Synthesis and Properties of tert-Butyliminovanadium(V) Compounds tC4H9N=VX3 (X = Cl, RCOO)

tC4H9N=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 tC4H9N=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 monomeric 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. - Key words: tert-Butyliminovanadium(V) Trichloride and Tricarboxylates, 1H NMR Spectra, IR Spectra
