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.
