Title:
RUTHENIUM COMPOUND AND METHOD FOR PREPARING OPTICALLY ACTIVE ALCOHOL COMPOUND
Document Type and Number:
WIPO Patent Application WO/2006/090479
Kind Code:
A1
Abstract:
A ruthenium compound represented by the following formula (I); an asymmetric hydrogenation catalyst comprising the above ruthenium compound; and a method for preparing an optically active alcohol compound, characterized in that a carbonyl compound is contacted with hydrogen in the presence of the above ruthenium compound. Ru(X)(Y)(Px)n(A) (I) [wherein each of X and Y represents a hydrogen atom, a halogen atom or the like, Px represents a phosphine ligand, n is 1 or 2, and A represents a diamine ligand represented by the following formula (1) or (2): R1CH(NH2)CH2(NR2R3) (1) R1CH(NR2R3)CH2(NH2) (2) (where R1 represents an alkyl group, an aryl group or the like having 1 to 20 carbon atoms, each of R2 and R3 represents a hydrogen atom, an alkyl group having 1 to 20 carbon atoms and optionally having a substituent, or the like)]
