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
