We report the hydrogenation of carbamates and urea derivatives, two of the most challenging carbonyl compounds to be hydrogenated, catalyzed for the first time by a complex of an earth-abundant-metal. The hydrogenation reaction of these CO2-derived compounds, cata-lyzed by a manganese pincer complex, yields methanol in addition to amine and alcohol, which makes this methodology a sustainable two-step route for the conversion of CO2 to methanol, involving a base-metal catalyst. Moreover, the hydrogenation proceeds under mild pressure (20 bar). Our observations support a hydrogenation mechanism involving the Mn-H complex. A plausible catalytic cycle is pro-posed based on informative mechanistic experiments.
