Versuchsvorschrift

In a 200 ml stirring type autoclave were charged 30 mmols of N,N'-diphenylurea, 15 mmols of nitrobenzene, 50 ml of methanol, 0.5 mmol of palladium chloride and 5 mmols of tetrabutylammonium iodide. After the air inside the autoclave had been replaced with carbon monoxide, carbon monoxide was pressurized into the autoclave to 140 Kg/cm2, and the reaction was carried out at 180° C. for 5 hours with stirring. As the result of analysis of the reaction solution obtained, the conversions of N,N'-diphenylurea and nitrobenzene were 26% and 33%, respectively, and 15 mmols of methyl N-phenylcarbamate were obtained.
