Title:
エステル又はラクトン類の水素還元によるアルコール類の製造方法
Document Type and Number:
Japanese Patent JP5477557
Kind Code:
B2
Abstract:
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)(L 1 )(L 2 ) n (1)
wherein
X represents a monovalent anionic ligand,
L 1 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
L 2 represents a bidentate aminophosphine ligand having one coordinating phosphino group and one coordinating amino group, provided that
n is 0 when L 1 is the tetradentate ligand, and n is 1 when L 1 is the bidentate aminophosphine ligand.
