A facile and selective procedure for oxidation of sulfides to sulfoxides with molecular bromine on hydrated silica gel in dichloromethane

Abstract

A new method for oxidation of sulfides to sulfoxides with molecular bromine on a solid silica gel support has been developed. This procedure cleanly oxidizes sulfides to the corresponding sulfoxides in excellent yields. To our knowledge, this is the first example of oxidation of sulfides by molecular bromine in dichloromethane that does not require the presence of a base or another reagent to scavenge the byproduct hydrogen bromide in order to prevent side reactions. The reported procedure is simple, fast, product isolation is trivial, and it produces excellent yields.
