Abstract

Cr(Salen) 1 is found to be an efficient catalyst for the oxidation of various sulfides to sulfoxides with iodosobenzene as terminal oxidant. Both aryl and alkyl sulfides are selectively converted into sulfoxides in excellent yields (>90%).

Key words

sulfide - sulfoxide - Cr(salen) - oxidation - selectivity
