Procedure

106 g (0.57 mol) of phenylvinylphosphinic acid chloride were dissolved in 150 ml of acetonitrile and stirred with 38 g (0.59 mol) of sodium cyanate at a temperature of 30° C. After 23 hours the precipitate was filtered off by suction and washed with acetonitrile. The filtrate was concentrated and the residue distilled at a temperature of 107°-110° C. and a pressure of 33 Pa. 84 g of phenylvinylphosphinic acid isocyanate (77% of theory) were obtained.
