Selective Oxidation of Sulfides to Sulfoxides Using IBX-Esters

Abstract

IBX-esters (esters of 2-iodoxybenzoic acid) are convenient hypervalent iodine reagents for the clean and selective oxidation of organic sulfides to sulfoxides. This reaction proceeds without over-oxidation to sulfones and is compatible with the presence of the hydroxy group, double bond, phenol ether, benzylic carbon, and various substituted phenyl rings in the molecule of the substrate.

Key words

hypervalent iodine - IBX-esters - sulfides - sulfoxides
