Abstract An efficient additive free hydrogenation of alkenes with molecular hydrogen is described. The pre‐catalyst a well‐defined bench stable Mn(I) alkyl complex bearing NHC phosphine ligand. These reactions are environmentally benign and atom economic, implementing an inexpensive, earth abundant non‐precious metal catalyst. catalytic process initiated by migratory insertion CO ligand into the Mn‐alkyl bond to yield acyl intermediate which undergoes rapid hydrogenolysis form active 16e hydride catalyst [Mn(PC‐ i Pr)(CO) 2 (H)]. A range mono‐ disubstituted were efficiently converted alkanes in good excellent yields. requires reaction temperature 60 °C. In all cases, loading 1 mol % pressure 50 bar was applied. mechanism based on DFT calculations presented supported experimental studies.
