A novel method for the formation of 2-arylsulfanylphenols using cyclohexanones as phenol source via dehydrogenation is described. Various aromatic sodium sulfinates and sulfonyl chlorides acted as efficient coupling partners to construct new C–S bonds in the presence of an iodine promoter.

2-(Phenylthio)phenols were successfully synthesized from simple phenols and aromatic halides by using dimethyl sulfoxide as the oxidant. The transformation was accomplished via tandem copper(I)-catalyzed C-S coupling/C-H functionalization employing the CuI/L [L = (E)-3-(dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-one] catalyst system. The mechanism of the reaction was elucidated based on an isotope
