    摘要: Provided is an alcohol production method comprising the step of reducing an ester or a lactone with hydrogen to produce a corresponding alcohol without addition of a base compound by using, as a catalyst, a ruthenium complex represented by the following general formula (1): RuH(X)(L1)(L2)n  (1) wherein X represents a monovalent anionic ligand, L1 represents a tetradentate ligand having at least one coordinating phosphino group and at least one coordinating amino group or a bidentate aminophosphine ligand having one coordinating phosphino group and one coordinating amino group, and L2 represents a bidentate aminophosphine ligand having one coordinating phosphino group and one coordinating amino group, provided that n is 0 when L1 is the tetradentate ligand, and n is 1 when L1 is the bidentate aminophosphine ligand.

    摘要: Esters and lactones can be respectively reduced to alcohols and diols in the presence of the Group 8 (VIII) transition metal complex, base and hydrogen gas (H2). An extremely practical reduction method can be provided by preferable combinations of the Group 8 (VIII) transition metal complex, the base, a used amount of the base, a pressure of hydrogen gas and a reaction temperature. This method is used in place of hydride reduction and is a useful method by which design of highly active catalysts can be relatively easily made while a high productivity can be expected.
