New vanadium oxodiperoxocomplexes Bu4N+[VO(O2)2 L2]− were synthesized, where L=pyridine (1), 2-methylpyridine (2), 4-methylpyridine (3), 2-oxymethylpyridine (4). All complexes were characterized by NMR (, ) and IR spectroscopy. The oxidation of sulfur organic compounds and diesel fuel desulfurization catalyzed by vanadium peroxocomplexes in bi-phase system was investigated in various solvents. The complexes manifested high catalytic activity and selectivity in oxidation of sulfides.

Novel vanadium peroxo complexes with pyridine ligands were prepared and characterized by NMR and IR spectroscopy and were shown to have activity in the selective oxidation of dialkyl and alkylaryl disulfides to corresponding sulfoxides.

Theophenol was shown to be oxidized with hydrogen peroxide under conditions of phase transfer catalysis in the presence of sodium metavanadate to afford benzenesulfonic acid, diphenyl disulfide, phenyl benzenesulfonate, and diphenyl sulfone. The yield of oxidation products increases with increasing temperature, catalyst concentration, and lipophilicity of the phase transfer catalyst.
