Abstract

Based on the diversity of ionic liquids, i.e. tunable structure and physicochemical properties, a series of functional ionic liquids and palladium complexes were investigated, and a highly effective catalyst system, Pd(phen)Cl₂-BAcImPF₆ ionic liquid (phen = 1,10-phenanthroline; BAcIm = 1-butyl-3-acetic acid-imidazolium), was developed for the reductive carbonylation of nitrobenzene to give the corresponding carbamate with higher than 90% of conversion and selectivity at 150 °C and 6 MPa carbon monoxide. The high catalytic performance is attributed to the acidic function of the BAcImPF₆ ionic liquid and the interaction between Pd(phen)Cl₂ and the ionic liquid to form the catalytically active palladium complex Pd(phen)₂(PF₆)₂.
