The Palladium-Catalyzed Intermolecular C–H Chalcogenation of Arenes
摘要:
Palladium catalyzes the intermolecular chalcogenation of carbazole, 2-phenylpyridine, benzo[h]quinolone, and indole derivatives with disulfides and diselenides via selective C-H bond cleavage, providing a convenient route to thio and selenoethers.

An unprecedented Cu(II)-mediated methylthiolation of aryl C-H bonds under oxidative conditions that employs the widely available DMSO as the methylthiolation reagent is described. Various functional groups in the substrates were tolerated, and ethylthiolation was also successfully achieved directly from diethyl sulfoxide under the same reaction conditions.
