Supported nanopalladium catalyst for C-C coupling reactions of haloarenes

摘要

The present invention relates to a novel process for the preparation of a reusable heterogeneous nanopalladium (o) catalyst, for preparing coupling products by C-C bond formation reaction of haloarenes that include unreactive chloroarenes in the presence of base.The catalyst is prepared by an exchange of PdCl₄^2- followed by reduction on the support selected from LDH and S'-NR₃X wherein S' is a unmodified surface support selected from resin and silica, R is an alkyl group selected from the group consisting of methyl, ethyl, propyl, butyl, X is selected from the group consisting of Cl, Br, I, F, OH and OAc.
