Ion exchange resin catalyzed selective oxidation of sulfides to sulfoxides using hydrogen peroxide

An efficient method for the selective oxidation of sulfides to sulfoxides under mild and environmentally safe conditions is achieved using hydrogen peroxide in the presence of Amberlyst 15 and Amberlite IR-400 at room temperature. This procedure can be applied for dialkyl and diaryl sulfides with a variety of functional groups. Functional groups such as hydroxyl, methoxy, amino, aldehyde, and olefinic double bonds remain intact.
