Provided is a catalyst for asymmetric reduction, which can be produced by a convenient and safe production method, has a strong catalytic activity, and has excellent stereoselectivity. The present invention relates to a ruthenium complex represented by the following formula (1): wherein R1 represents an alkyl group or the like; Y represents a hydrogen atom; X represents a halogen atom or the like; j and k each represent 0 or 1; R2 and R3 each represent an alkyl group or the like; R11 to R19 each represent a hydrogen atom, an alkyl group or the like; Z represents oxygen or sulfur; n1 represents 1 or 2; and n2 represents an integer from 1 to 3, a method for producing the ruthenium complex, a catalyst for asymmetric reduction formed from the ruthenium complex, and methods for selectively producing an optically active alcohol and an optically active amine using the catalyst for asymmetric reduction.

Newly developed oxo-tethered Ru amido complexes (R,R)-1 and their HCl adducts (R,R)-2 exhibited excellent catalytic performance for both asymmetric transfer hydrogenation and the hydrogenation of ketonic substrates under neutral conditions without any cocatalysts to give chiral secondary alcohols with high levels of enantioselectivity.
