ABSTRACT:
A ruthenium-phosphine complex represented by formula (I):
[RuH.sub.l (R-BINAP).sub.m ]X.sub.n' (I)
wherein R-BINAP is a tertiary phosphine represented by formula (II): ##STR1## R is a hydrogen atom or a methyl group; X is a ClO.sub.4, BF.sub.4, or PF.sub.6 ; and when l is 0, then m is 1 and n' is 2, and when l is 1, then m is 2 and n' is 1, is disclosed. The complex is inexpensive and exhibits excellent performances as a catalyst for various organic syntheses, and particularly for asymmetric hydrogenation.
