Palladium-catalyzed coupling reaction of diaryl dichalcogenide with aryl bromide leading to the synthesis of unsymmetrical aryl chalcogenide

摘要

An efficient cross-coupling reaction of diphenyl disulfide or diselenide with substituted aryl bromides using PdCl2(dppf) and zinc has been developed. This method gave functionalized unsymmetrical aryl sulfides and selenides in good to excellent yields under neutral conditions.
