Palladium-Catalyzed Desulfitative Arylation by C–O Bond Cleavage of Aryl Triflates with Sodium Arylsulfinates

Abstract

An efficient Pd-catalyzed desulfitative coupling reaction of sodium arylsulfinates as arylation reagents by C-O bond cleavage of aryl triflates was developed. With only 2 mol % of Pd(OAc)(2) as catalyst and XPhos as ligand, the reaction proceeded well for a range of substrates.
