摘要

The platium catalyst combined with triphenylphosphine, tin (IV) chloride, and triethylamine showed high activity for the reductive N-carbonylation of nitroarene in ethanol at 180° C under carbon monoxide of 60 kg cm− 2. From nitrobenzene, ethyl phenylcarbamate was obtained in 83% yield. Iron (III) chloride, aluminum chloride and titanium (IV) chloride could be used as Lewis acids in place of tin (IV) chloride. Various nitroarenes were transformed ...
