A protocol for palladium-catalyzed C–H carbonylation of readily available free primarybenzylamines using NH2 as the chelating group under an atmospheric pressure of CO has been achieved, providing a general, atom- and step-economic approach to benzolactams, an important structural motif found in many biologically active compounds. Application of this new method is also exemplified in the concise syntheses
