Abstract

A direct selective approach to the oxidation of sulfides to sulfoxides and sulfones with H₂O₂ in moderate to good yields is developed. The reaction proceeds in the presence of 2 mol % of VO(acac)₂ at room temperature. All sulfoxides and sulfones were detected by gas chromatography, and the molecular structures of 2-methylbenzyl 4-methylphenyl sulfone, 4-methylbenzyl 4-methylphenyl sulfone, 2-bromobenzyl 4-methylphenyl sulfone, and 4-tert-butylbenzyl benzyl sulfone were determined by single crystal X-ray crystallography.
