1. A sulfonate catalyst represented by general formula (1) and used for a hydrogenation reaction:
 R1 and R2 may be the same or different and each represent an alkyl group, a phenyl group, a naphthyl group, or a cycloalkyl group, which
may be substituted, or a part of an alicyclic ring formed by bonding of R1 and R2;
R3 represents an alkyl group, a phenyl group, a naphthyl group, or camphor which may be substituted;
R4 represents a hydrogen atom or an alkyl group;
R5 represents an alkyl group, a phenyl group, a naphthyl group, or camphor which may be substituted;
Ar is bonded to M1 through a π bond and represents benzene which may be substituted or a cyclopentadienyl group which may be substituted;
M1 represents ruthenium, rhodium, or iridium; and
* represents a chiral carbon.
