We have developed a divergent strategy for the synthesis of five- and six-membered lactams via either an amidation of sp3 C-H bonds or electrophilic substitution of arenes via Ir-nitrene intermediates. With the employment of a readily available iridium catalyst in dichloromethane or hexafluoro-2-propanol, a wide range of lactams were synthesized in good to excellent yields with high selectivity.
