Title:
ION-EXCHANGE RESINS CARRYING PALLADIUM IMMOBILIZED THEREON AND PROCESS FOR REDUCTION WITH THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/028146
Kind Code:
A1
Abstract:
The invention provides ion-exchange resins carrying palladium immobilized thereon which can withstand repeated use, have functional group selectivity, and can be used more easily. The invention relates to palladium-carrying ion-exchange resins obtained by immobilizing palladium on ion-exchange resins having groups resulting from ethylenediamine as the ion-exchange group; and a process for the reduction of compounds having functional groups selected from among -N3, -NO2, -CHO and -CO2CH2-Ar (wherein Ar is optionally substituted aryl), compounds having -C≡C- or -C=C-, or compounds represented by the general formulae: Ar-COR, Ar-X and Ar-NHCbz (wherein Ar is optionally substituted aryl; R is optionally substituted alkyl; X is halogeno; and Cbz is benzyloxycarbonyl), characterized by bringing the compounds into contact with the above palladium-carrying ion-exchange resin.
