Reaction Steps

The procedure of Example 14 is repeated using 12.3 parts of nitrosobenzene, 80 parts of benzene, 10 parts of 5% palladium on carbon and 0.44 part of stannic chloride. After carbon monoxide is introduced to a pressure of 4,000 p.s.i., the pressure vessel is heated at 190°C. for 5 hours. Phenyl isocyanate is obtained.
