An efficient transition-metal-free intermolecular benzylic amidation with sulfonamides is described. Various valuable nitrogen-containing compounds, including amines, beta-chloro amine, amino alcohol, alpha-, beta-amino ester, and N-sulfonyl imine, are generated from the preferential N-functionalization of saturated benzylic C-H bonds. The potential of this reaction system also lies in the fact it can be developed into an environmentally friendly intermolecular amidation process.
