N-heterocyclic carbene-catalyzedoxidationusingTEMPO is reported for the conversion of aldehydes to amides. A wide range of amides were synthesized in good yields (up to 72%) via a one-pot, sequential protocol involving oxidative esterification of aldehydes and subsequent aminolysis. To promote efficient aminolysis, various alkoxide leaving groups were evaluated.

A MnI complex coordinated with a redox non-innocent phenalenyl (PLY) ligand is reported for catalytic N-formylation of secondary amides (including late-stage diversification of pharmaceutics) and lactams with CO2 as C1 source at room temperature for the first time. A combined approach of experimental analysis and DFT calculations sketch the plausible radical-mediated pathway of an unconventional metal-ligand
