Title:
CATALYST CONTAINING ACTIVATED CARBON ON WHICH RUTHENIUM COMPLEX IS ADSORBED, AND METHOD FOR PRODUCING REDUCTION PRODUCT USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/177287
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a catalyst which exhibits high reusability and is capable of reducing the amount of residual metals in a reaction liquid in a process wherein an optically active reduction product is produced by an asymmetric reduction reaction of an organic compound. The present invention relates to a catalyst that contains an activated carbon on which a ruthenium complex represented by general formula (1-1) and/or (1-2) is adsorbed. (In the formulae, j, k, X, Y, and R1 to R10 are as defined in claim 1.)
