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
