Procedure

166 g (1.2 mol) of allylmethylphosphinic acid chloride were dissolved in 300 ml of acetonitrile and heated with 78 g (1.2 mol) of sodium cyanate to 50°-55° C. while stirring. After 5.5 hours, the precipitate was filtered off by suction and washed with acetonitrile. The filtrate was then concentrated and the residue distilled at a temperature of 78°-80° C. and at a pressure of 25 Pa. 123 g of allylmethylphosphinic acid isocyanate (71% of theory) were obtained.
