ABSTRACT
Efficient hydrogenations of terminal alkenes with molecular hydrogen catalyzed by well-defined bench stable Mn(I) complexes containing an N-heterocyclic carbene-based PCP pincer ligand are described. These reactions are environmentally benign and atom economic, implementing an inexpensive, earth abundant non-precious metal catalyst. A range of aromatic and aliphatic alkenes were efficiently converted into alkanes in good to excellent yields. The hydrogenation proceeds at 100 °C with catalyst loadings of 0.25-0.5â
mol %, 2.5-5â
mol % base (KOt Bu) and a hydrogen pressure of 20â
bar. Mechanistic insight into the catalytic reaction is provided by means of DFT calculations.
