Insertion of benzene rings into the amide bond using the reactive intermediate benzyne is described. Aromatic amides undergo smooth insertion when treated with O-triflatophenyl silane benzyne precursors, producing versatile aminobenzophenone products in good to excellent yield. The process is entirely metal-free and has been exemplified on the synthesis of biologically active acridones and acridines

A copper-catalyzed approach for the synthesis of acridones via C–Cbondcleavage and intramolecular cyclization using air as the oxidant under neutral conditions is described. This transformation offers an alternative method to prepare medicinally important acridones and a new strategy for C–Cbondcleavage.
