ABSTRACT:
The invention relates to a chiral iridium aqua complex of formula (1):wherein R1and R2are the same or different and each is an aryl group optionally having at least one substituent selected from the group consisting of a halogen atom, an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a haloalkoxy group having 1 to 6 carbon atoms, a nitro group, a carboxyl group and a cyano group, or the like; and wherein R3and R4are the same or different and each is an alkyl group or the like, as well as the use of such a chiral iridium aqua complex for asymmetric transfer hydrogenation.
