Free or unfunctionalized benzylamines are well known to participate in C–H activation in the presence of palladium salts. Despite the ease with which these complexes can be activated, subsequent functionalization of the dimeric cyclometalates can be challenging. We demonstrate herein a free primary amine based C–H activation/functionalization protocol that allows for the ortho-C–H chlorination and

The generation of benzylicradicals through hydrogenatomabstraction (HAT) has been a recent research focus and various C(sp3)−H bond functionalization protocols have been developed relying on this elementary step. We report herein copper- and iron-catalyzed C(sp3)−H benzylic azidation reactions using mCPBA and NFSI as oxidant, respectively, and TMSN3 as azide source. The reaction is thought to be
