Procedure

170 g (1.1 mol) of crotylmethylphosphinic acid chloride were dissolved in 300 ml of acetonitrile and heated with 73 g (1.1 mol) of sodium cyanate to 55° C. while stirring. After 4.5 hours, the precipitate was filtered off by suction and washed with acetonitrile, the filtrate was concentrated, and the residue distilled at a temperature of 76°-78° C. and at a pressure of 27 Pa. 123 g of crotylmethylphosphinic acid isocyanate (70% of theory) were obtained.
