Abstract
The present invention has as its object to provide an iridium complex represented by the general formula:[(I r H LL)(μ−X)(μ−X)(μ−X)]X  (1)(wherein Land Lmay be the same or different and each represent a monodendate neutral ligand, or each cooperate with the other to form a bidendate neutral ligand; X, Xand Xmay be the same or different, and each represent a halogen atom; and Xis a counter-anion). Also, the present invention provides a novel catalyst which can achieve excellent performance as a catalyst for asymmetric synthesis, especially asymmetric hydrogenation, in terms of chemical selectivity, enantioselectivity and catalytic activity, and the like.
