NOVEL RUTHENIUM COMPLEX AND PROCESS FOR PRODUCING OPTICALLY ACTIVE ALCOHOL COMPOUND USING SAME AS CATALYST
-
Paragraph 0064, (2014/03/21)
The present invention provides: a novel ruthenium complex which has excellent catalytic activity with respect to reactivity in the reduction of a multiple bond, in particular, in the asymmetric reduction of a carbonyl compound, enantioselectivity, etc.; a catalyst which comprises the ruthenium complex; and a process for producing optically active compound, in particular, an optically active alcohol compound, using the catalyst. The ruthenium complex has a ruthenacyclic structure. The catalyst is a catalyst for asymmetric reduction which comprises the ruthenium complex.

This invention is concerned with a ruthenium-iodo-optically active bidentate phosphine complex of the formula (I):[Ru-(I)q-(T1)n(SOL)r(L)]m(T2)p(I)s(I)wherein T1 represents a carboxylic acid anion, SOL represents a polar solvent, L represents an optically active bidentate phosphine ligand, T2 represents an anion different from halogen atom anions and carboxylic acid anions, n denotes 0 or 1, r denotes 0, 3 or 4, m denotes 1 or 2, q denotes 0 or 1, or where m is 2, q may represent 1 or 1.5, p denotes 0 or 1, and s denotes 0, 1 or 2 is prepared. Said phosphine complex is usefull as an efficient catalyst for asymmetrically hydrogenating 4-methylene-2-oxetanone into optically active 4-methyl-2-oxetanone.
