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

metal-free remote oxidative benzylic C−Hamination of 4-methylanilides with N-fluorobenzenesulfonimide was reported. The reaction was promoted by a hypervalent iodine reagent and can be handled undermild and neutral conditions, providing the highly regioselective benzylic C−Hamination products even with multi-substituted 4-methylanilides. It provided a novel and facile method for the construction of C(sp3)–N
