A mild, efficient and environmentally friendly oxidation of sulfides to sulfoxides with a recyclable ion-supported hypervalent iodine reagent tolerates hydroxyl, nitrile, methoxy, carbon-carbon double bonds, and ester functionalities. Aliphatic and aromatic sulfides are selectively oxidized to the corresponding sulfoxides at room temperature in excellent yields without over-oxidation.
