A copper-catalyzed sulfoxidation of benzylic C–H bonds by nondirected oxidative C(sp3)-H activation was developed. The process proceeds via sulfenate anions, which are generated by base-triggered elimination of β-sulfinyl esters and benzyl radicals. The functional group tolerance is high, and the product yields are good.

Enantiopure aryl benzyl sulfoxides can be prepared using vanadium-Schiff base catalyzed sulfide oxidation and kinetic resolution of the resulting sulfoxide. The kinetic resolution can be effected in combination with asymmetric sulfide oxidation or instead starting from the racemic sulfoxide.
