Palladium-Catalyzed Distal Selective C–H Chalcogenation of Biphenyl Amines

Herein, we describe a palladium-catalyzed distal C–H chalcogenation of biphenyl amines, affording a series of valuable aryl chalcogenides, which could be further transformed to 8-membered N, Se(S)-heterocycles through intramolecular C–N cyclization.
