A novel method for the formation of 2-arylsulfanylphenols fromthiols and cyclohexanones is described. Iodine was used as an effective catalyst for this kind of transformation. Cyclohexanones were used as a phenol source via a dehydrogenation and tautomerization reaction.

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

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
A protocol with available starting materials and mild conditions was developed for the synthesis of polysubstituted phenols and functionalized carbocycles via acylation of electron-poor alkenyl sulfoxides. The plausible mechanism was investigated.
