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- (THF)2] upon oxidation with elemental sulfur; 11 has been characterized by 51V NMR spectroscopy.

Abstract The oxovanadiumhalidesVOCl2·2Py (1), VOCl2·3Py (2) and VO2Cl·2Py (3) have been isolated as unexpected products from reactions between VCl4 and VOCl3, respectively, with [(Ph2SiOM′)2O] (M′Li or Na). Further reaction of compound 1 with [O(SiPh2OLi)2·2THF], however, gave the cyclosiloxyoxovanadium(IV) complex [VOO(SiPh2O)22-μ-(Li(THF)2)2]. The manner in which 1, 2 and 3 may be formed in these
