Title:
OPTICALLY ACTIVE IRIDIUM COMPLEX AND USE
Document Type and Number:
Japanese Patent JPS62281861
Kind Code:
A
Abstract:
Optically active iridium complexes of the formula in which R is methyl and R1 is a hydrocarbon radical having at least one chiral C atom or a hydrocarbon radical containing at least one hetero atom and having at least one chiral C atom; or R is a hydrogen atom and R1 is 1,2-diphenylethyl or a 5-membered or 6-membered cycloaliphatic or cycloheteroaliphatic radical having at least two chiral C atoms and a phenyl group or alkyl group in the alpha -position, X(-) is an anion of a monobasic inorganic or organic acid and Y and Z are each ethylene, or Y and Z together represent an open-chain or cyclic diene which has 6 to 10 C atoms and whose diene groups are bonded via 1 or 2 C atoms. They are suitable as enantioselective, homogeneous catalysts for the transfer hydrogenation of, in particular, prochiral ketones with secondary alcohols.
