An alkali metal sulfonate-substituted binaphthyl-phosphine transition metal complex is represented by the formula:
[M(X)n(Q) (SO₃A-BINAP)]Y (I)
wherein M represents an atom of a transition metal such as Rh, Ir, P or Ru, SO₃A-BINAP represents a tertiary phosphine represented by formula (II)
in which A represents an alkali metal atom;
X represents a chlorine, bromine or iodine atom;
when n is 1, M represents ruthenium, Q represents benzene or p-cymene , and Y represents a chlorine , a bromine or iodine atom;
when n is 0 and M is iridium or rhodium, Q represents, 1,5-cyclo-octadiene or norbornadiene, and Y represents ClO₄, PF₆ or BF₄; and
when n is 0 and M is palladium, Q represents π-allyl, and Y represents ClO₄, PF₆ or BF₄.
A method of enantioselectively hydrogenating an olefin, a ketone or an imine, comprises carrying out the enantioselective hydrogenation using as a catalyst the complex of formula (I).
