The catalytic activities of rhodium(I) complexes in the carbonylation of phenyl azide at atmospheric pressure, leading to the corresponding isocyanate have been studied. Cl and RhCl(CO)(PPh3)2 are the most active catalysts, and maintain their high activity even in the presence of aniline (which gives diphenylurea) or ethanol (which gives carbamate).
