In this strategy, a secondary amine is first formylated by CO 2 and H 2 to make H 2 O and formamide. The formamide then undergoes decarbonylation to produce CO with the concomitant regeneration of the amine. Both steps, formylation and decarbonylation, were independently investigated through catalytic optimization studies and DFT computations at the PBE0-D3(BJ) PCM(THF) /def2-TZVP level. Using morpholine and Ru-MACHO pincer catalyst, a TON of 249 was achieved for the hydrogenation of CO 2 to CO (at 70 bar, 170 °C for 90 h) with 100% selectivity.
