The thermal reaction of phosphinimines with alkyl-substituted chromium(0) Fischer carbenecomplexes is reported. The process occurs through a metathesis-like reaction to yield stable chromium imidate complexes. The formation of the azametallacycle 15 from zwitterion 14 is the key to the process. The length of the phosphinimine tether, the electrophilicity of the imine moiety, and the bulkiness of the

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.
