Cross-dehydrogenative C-N annulations and dealkylative C-N annulations of 2′-N-aryl/alkylaminoacetophenones and 2′-N,N-dialkylaminoacetophenones respectively in the presence of Cu(OAc)2ĚH2O, NaOAc and air gave isatins in good yields. However, on reaction with CuBr, 2′-N-benzylaminoacetophenones underwent selective oxidation at the benzylic position to provide the corresponding benzamides exclusively.
