In the process of reductive carbonylation of nitrobenzene to carbamates, another reduction reaction of nitrobenzene to amine proceeded at the same time. By investigation of various reaction conditions, it is found that the selectivity of reductive carbonylation of nitrobenzene can be remarkably increased by using PVP as a carrier, incorporating FeCl_3 as a second metal component, and raising the temperature. When the organic ligands were replaced by inorganic compound, high selectivity was achieved by a synergic effect of bimetallic systems.
