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.

degradation of the Schiffbase gives more hemiacetal (HL1a) and the final product, the monomeric complex [ReOCl(L1a)2] is formed. Cleavage of the organic framework is not observed during the reaction of (NBu4)[ReOCl4] with a related Schiffbase derived from ethylene-1, 2-diamine and (2-formylphenyl)diphenylphosphine. The Schiffbase reacts as a bis-bidentate N, P ligand and a dinuclear oxorhenium(V) compound

2-diaminoethane. Some complexes could also be obtained for the first time in a one-pot template synthesis under mild reaction conditions. Single crystalX-ray diffraction studies of the complexes revealed a trans distorted octahedral structure around the iron. The iPr or Ph substituents on the diamine were found to be axial in the five-membered Fe−N−CHR−CHR−N− ring of the chiral P−N−N−P ligands. A steric

NMR and Raman spectroscopy. In the case of Ph2P(I2)(CH2)nP(I2)Ph2 (n = 2 or 4), 31P-H} NMR magic angle spinning NMR spectroscopy has been used to investigate the nature of the compounds in the solidstate. In agreement with our previous extensive studies on the monophosphine derivatives, R3PI2, the tetraiododiphosphine compounds Ph2P(I2)(CH2)nP(I2)Ph2 (n = 2 or 4) isolated from diethyl ether contain
