A mild, efficient, highlyselective, and environmentally friendly oxidation of sulfides to sulfoxides with a recyclable ion-supportedhypervalentiodinereagent has been developed. This reaction is tolerant of hydroxyl, nitrile, methoxy, carbon-carbon double bonds, and ester functionalities. Aliphatic and aromatic sulfides are selectively oxidized to the corresponding sulfoxides at room temperature

The asymmetricoxidation of sulfides to chiral sulfoxides with hydrogen peroxide in good yield and high enantioselectivity has been catalyzed very effectively by chiral vanadium−salan [N,N‘-alkyl bis(salicylamine)] complex. The salan ligand shows results superior in terms of reactivity and enantioselectivity to those of salen [N,N‘-alkylene bis(salicylideneimine)] analogue, and provides the sulfoxide

The kinetics of the oxidation of number of aryl methyl, alkyl phenyl, dialkyl and diphenyl sulphides by permanganate ion to yield the sulphoxides, have been studied. The reaction is first order with respect to the sulphide and permanganate and is independent of hydrogen ion concentration. The reaction exhibited negative polar reaction constants and a small degree of steric hindrance. The lack of solvent
