文摘
A CuI-catalyzed direct access to sulfides from disulfides via C−H bond cleavage of di- or trimethoxybenzene is described. The procedure utilizes O2 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.
