Manganese(I) complexes bearing simple, non-bifunctional bis(NHC) ligands were investigated as hydrogenation catalysts. Applying these complexes with KHBEt3 as additive, various carboxylic acid esters and, additionally, ketones, nitriles, N-heteroarenes and alkenes were successfully hydrogenated. Mechanistic investigations by control experiments and DFTcalculations indicate an inner-sphere mechanism and reveal
