An efficient copper-mediated dithiolation of C(sp2)—H bonds with aryl thiols was achieved by using amide-oxazo- line as directing group. This strategy gives a variety of functionalized thioethers in moderate to excellent yields (up to 90%) in simple and efficient way. Importantly, the substrate scope is not limited to various substituted phenylamides, and diverse pyridine amides are also compatible. Furthermore, the protocol has been successfully implemented for the gram-scale synthesis as well.

Key words: copper, C—H bond, thiolation, amide-oxazoline, aryl thiols
