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

In this work, an efficient CuSO4-catalyzed S-arylation of thiols with aryl and heteroaryl boronic acids at room temperature is established. This catalytic system can an tolerate a wide variety of thiols and arylboronic acids in the presence of only 5 mol % of CuSO4 as the catalyst and inexpensive 1,10-phen center dot H2O as the ligand. Moreover, this catalytic system used environment-friendly solvent (EtOH) and oxidant (oxygen).
