The bis(carbonyl) manganese(I) complex [Mn(CO) 2 ( 1 )]Br ( 2 ) with a chiral (NH) 2 P 2 macrocyclic ligand ( 1 ) catalyzes the asymmetric transfer hydrogenation of polar double bonds with 2‐propanol as the hydrogen source. Ketones (43 substrates) are reduced to alcohols in high yields (up to >99 %) and with excellent enantioselectivities (90–99 % ee ). A stereochemical model based on attractive CH–π interactions is proposed.
