sulfur). Here, the disulfide‐directed C–H activation for thew synthesis of sulfonyl diphenyl sulfides was realized for the first time by a copper‐catalyzed, tandem, one‐step C–S coupling/hydroxylation of disulfides and arylboronic acids with oxygen as the oxidant. This method provides a mild and easy method for the synthesis of sulfonyl diphenyl sulfides and 2‐(phenylthio)phenol derivatives and avoids producing

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

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

disulfide-directed Csp2–H hydroxylation cascade reaction strategy catalyzed by Cu2(TPTC), a metal–organic framework material with binuclear Cu(II) paddlewheel nodes. In the strategy, Cu2(TPTC) MOF can effectively catalyze the coupling reaction of disulfide and arylboronicacid, and realize the disulfide-directed Csp2–H hydroxylation reaction. This reaction proceeded well under Cu2(TPTC) MOF catalyst with good yields
