An unprecedented zinc triflate catalyzed selective C-benzylation of anilides and heteroaryl amides with benzylchlorides having electron-donating group at para-position is reported. The protocol offers moderate to high yield of para-amido substituted diaryl and arylheteroarylmethanes, uses cheap and easily available benzylchlorides as the benzylating agent, catalytic amount of zinc triflate, and takes
