Palladium-Catalyzed Suzuki−Miyaura Cross-Couplings of Sulfonyl Chlorides and Boronic Acids

Abstract

[reaction: see text] R = tolyl, phenyl, 4-halophenyl, 1-naphthyl, 2-nitrophenyl, benzyl, methallyl, r1 = aryl, heteroaryl, alkenyl. Arene-, arylmethane, and alk-2-ene-1-sulfonyl chlorides undergo Suzuki-Miyaura cross-coupling with arene-, heteroarene-, and alkeneboronic acids in THF at reflux. The reactivity order is ArI > ArSO(2)Cl > ArBr >> ArCl.
