Copper‐catalyzed thiophenol C−Hactivation is described. Through an initial attempt to conduct C‐arylation with arylboronic acid, a rather surprising sequential C−Hactivation and S‐arylation was discovered. Mechanistic investigation revealed the disulfide intermediate as the key component in directing C−Hoxidation. The overall reaction proceeded under mild conditions with molecular oxygen as the

A convenient and simple method for copper-catalyzed synthesis of 2-(arylthio)phenols through C–H functionalization of arylthiols and aryl iodides was developed under ligand-free conditions without nitrogen protection. In addition, arylthioquinone derivatives were very easily prepared for one more step of oxidation with moderate to good yields. This provide an alternative and efficient way to 2-(arylthio)phenols
