The asymmetric oxidation of sulfides to chiral sulfoxides with hydrogen peroxide in good yield and high enantioselectivity has been catalyzed very effectively by a chiral vanadium-salan complex. The efficient kinetic resolution of racemic sulfoxides catalyzed by the vanadium-salan system is also described.
