<p>An iridium complex represented by the general formula (1): [Chemical formula 1] [(IrHL<SUP>1</SUP>L<SUP>2</SUP>)<SUB>2</SUB>(µ-X<SUP>1</SUP>)(µ-X<SUP>2</SUP>)(µ-X<SUP>3</SUP>)]X<SUP>4</SUP> (1) (wherein L<SUP>1</SUP> and L<SUP>2</SUP> may be the same or different, and each represents a unidentate neutral ligand or L<SUP>1</SUP> and L<SUP>2</SUP> in combination form a bidentate ligand; X<SUP>1</SUP>, X<SUP>2</SUP>, and X<SUP>3</SUP> may be the same or different and each represents halogeno; and X<SUP>4</SUP> represents a counter anion). Also provided is a novel catalyst which has excellent performances with respect to chemical selectivity, enantioselectivity, catalytic activity, etc. when used as a catalyst for asymmetric synthesis reactions, especially asymmetric hydrogenation.</p> |
