A phenyltrimethylammonium tribromide-mediated nucleophilic substitution/oxygen transformation reaction of benzyl halides with DMSO has been developed. In this transition-metal-free reaction, DMSO acts as not only a solvent but also a "S(O)Me" source, thus providing a convenient method for the efficient and direct synthesis of various benzyl methyl sulfoxides.

The Sharpless reagent for asymmetric epoxidation was modified by addition of 1 mol equiv of H2O to give a new homogenous reagent (Ti(O-i-Pr)4/diethyl tartrate/H2O/t-BuOOH = 1:2:1:1).This reagent cleanly oxidizes prochiral functionalized sulfides into optically active sulfoxides.The observed ee mainly ranged between 75 and 90percent for alkyl aryl sulfoxides and 50-71percent for dialkyl sulfoxides.A strong temperature dependence on ee was also observed in the asymmetric oxidation of methyl p-tolyl sulfoxide.
