C−S Cross‐Coupling of Aryldiazonium Salts with Thiols Mediated by Gold

Abstract

AbstractIn this work, the coupling of aryldiazonium salts with thiols mediated by the readily accessible gold complex Me2SAuCl is described. In the reported protocol, the addition of 2,2′‐bipyridine as a ligand leads to higher yields than phosphines. The reaction proceeds at room temperature under soft mildconditions and has a broad scope in both the aryldiazonium salt and the thiol. Notably, the coupling works with aryldiazonium salts containing two additional substituents.
