The treatment of complexes 2aa, 2ac, 2ad, 2ba, 2bc, and 2bd with CO at 50 °C affords the corresponding benzo[d]azocine-2,4(1H,3H)-diones (3), which result from the insertion of a molecule of CO into the Pd–C bond and subsequent C–N reductive coupling and formation of (tmedaH)TfO. The reaction of 2ab with CO in MeOH gives (MeO2C)2C═C(CO2Me)C6H4CH2C(O)NH2-2 (4ab). Complexes 2aa and 2ab react
