Abstract
The present invention provides a novel ruthenium complex which has an excellent catalytic activity in terms of reactivity for asymmetric reduction of a carbonyl compound and enantioselectivity, a catalyst using the ruthenium complex, and a method for preparing optically active alcohol compounds using the ruthenium complex. The present invention relates to a ruthenium complex having ruthenacycle structure, a catalyst for asymmetric reduction consisting of the ruthenium complex, and a method for preparing optically active alcohol using the ruthenium complex.
