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

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
Trypanothionereductase (TR) is an essential enzyme of trypanosomatids and therefore a promising target for the development of new drugs against African sleeping sickness and Chagas' disease. Diaryl sulfides with a central anilino moiety, decorated with a flexible N-alkyl side chain bearing a terminal ammonium ion, are a known class of inhibitors. Using computer modelling, we revised the binding model
