Chan–Lam-Type S-Arylation of Thiols with Boronic Acids at Room Temperature

Abstract

In this work, an efficient CuSO(4)-catalyzed S-arylation of thiols with aryl and heteroaryl boronic acids at room temperature is established. This catalytic system can tolerate a wide variety of thiols and arylboronic acids in the presence of only 5 mol % of CuSO(4) as the catalyst and inexpensive 1,10-phen·H(2)O as the ligand. Moreover, this catalytic system used environment-friendly solvent (EtOH) and oxidant (oxygen).
