Abstract

Abstract An efficient cross-coupling reaction of diphenyl disulfide or diselenide with substituted aryl bromides using PdCl 2 (dppf) and zinc has been developed. This method gave functionalized unsymmetrical aryl sulfides and selenides in good to excellent yields under neutral conditions.
