A CuI-catalyzed direct access to sulfides from disulfides via C-H bond cleavage of di- or trimethoxybenzene is described. The procedure utilizes O-2 as a clean and cheap oxidant. Direct selenation of the C-H bond also took place under this procedure. Furthermore, the system enables the use of two RS in (RS)(2). Thus, it represents an atom-economical procedure for the synthesis of sulfides and selenides.
Iron-Catalyzed Direct C-H Thiolation of Trimethoxybenzene with Disulfides
An iron-catalyzed thiolation access to sulfides from disulfides via arene C-H bond cleavage of trimethoxybenzene is described. The procedure tolerates methoxyl, fluoro, chloro, bromo, nitro, and heterocyclic groups, using air as the clean and terminal oxidant.
Metal-and Oxidant-Free Electrochemical Synthesis of Aryl Sulfides
A metal- and oxidant-free electrochemical synthesis of aryl sulfides was developed through a C–H sulfidation reaction of arenes and disulfides. Compared with traditional organic synthesis methods, this direct electrochemical approach efficiently generates aryl sulfides under catalyst- and oxidant-free conditions with the superiorities of wide substrate compatibility, mild reaction condition and waster
