An efficient Ru catalyst constructed from simple and commercially available triphenylphosphane and enantiopure (1S,1′S)‐1,1′‐biisoindoline (BIDN) was applied to the asymmetric hydrogenation of aromatic ketones. A range of simple aromatic ketones could be hydrogenated with good to excellent enantioselectivities (up to 95 % ee). An appropriate enantioselective transition state was proposed to explain
