Polymer-supported Palladium-based Bimetallic Catalysts for the Oxidative Carbonylation of Aniline

Abstract

Abstract: Polymer-supported bimetallic catalyst PVP-PdCl₂-MnCl₂[PVP=poly(N-vinyl-2-pyrrolidone] exhibits a high activity and selectivity for the oxidative carbonylation of aniline to carbamate ester under atmospheric pressure [v(CO)/V(O₂)=10/1]. A remarkable bimetallic synergic effect in PVP-PdCl₂-MX_n(M: second transition metal) gives rise to an obvious increase in the conversion and selectivity for the reaction in the presence of a base(NaOAc). Among the Mcomponents tested, Mn-Pd exhibits the strongest synergic effect.

Key words: PVP-PdCl₂-MnCl₂bimetallic catalyst, Oxidative carbonylation, Synergic effect, Ethyl N-phenylcarbamate
