The first amide-directed, palladium-catalyzed, intermolecular, highly selective C-H aminations with the non-nitrene-based nitrogen source N-fluorobenzenesulfonimide have been developed. This methodology might provide a new pathway for directed metal-catalyzed aromatic C-H amination.

An unprecedented remote amide-directed palladium-catalyzedintermolecularhighly selective benzylic C-H amination with N-fluorobenzenesulfonimide is developed, which represents the first direct benzylic C-H amination with a non-nitrene nitrogen source. This methodology provides a novel approach to circumvent the common ortho aromatic C-H selectivity in directed palladium catalyzed C-H functionalization
