Syntheses of oxovanadium(V) thiolates such as O = V(SR)3 (R = tC4H9, SiPh3) and O = V(OtC4H9)n(StC4H9)3-n (n = 1, 2) are described.The thiovanadium(V) compounds S = V(OtC4H9)3, S = V(StC4H9)(OtC4H9)2 and S = V(SSiPh3)3 have been prepared by various methods: substition using Lawesson reagent, oxidation of V(OtC4H9)4 by sulfur, or disproportionation reaction of VCl4 with LiSSiPh3; O = V(OSiR3)3 (R = Me, Ph) undergoes a reaction with Lawesson reagent to yield dithiophosphonate complexes.All compounds obtained are characterized by 1H and 51V NMR spectroscopy; the stability of thiovanadium(V) compounds is discussed.V(StC4H9)4 has been sythesized as a first example of vanadium(IV) thiolates. - Key words: Thiolato Oxovanadium(V), Thiolato Thiovanadium(V), Preparation, 51V NMR Spectra
