A palladium-catalyzed arylation of aryl sulfenate anions generated from aryl 2-(trimethylsilyl)ethyl sulfoxides and CsF has been developed. This protocol is effective for the synthesis of diaryl sulfoxides and heteroaryl aryl sulfoxides under mild conditions employing aryl bromides. Various functional groups, including those with acidic protons, are well tolerated.
