Patent abstract
A method for producing alcohols which comprises reducing esters or lactones with hydrogen gas in the presence of a catalyst comprising (i) a ruthenium compound, (ii) a monodentate monophosphine or a bidentate bisphosphine, and (iii) an amine. Examples of the catalyst include a ruthenium (Ru) complex represented by the formula:RuX1X2(LP)m(LN)n [X1 and X2 each represent an anionic ligand, LP represents a phosphine ligand, m is 1 when LP is bidentate, while m is 2 when LP is monodentate, LN represents an amine ligand, and n is 1 when LN is bidentate, while n is 2 when LN is monodentate.] and a catalyst comprising an amine and a ruthenium (Ru) complex of the formula: RuX1X2(LP1)r [LP1 represents a monophosphine ligand and r is 3 or 4.].
