HCID 19090907Ethyl 2-cyanoethyl(phenyl)phosphinate

Procedure

To 42.45 g of phenylphosphonous acid-ethylester and 16.45 ml of acrylonitrile are added with stirring 5 ml of sodium ethylate (1 molar). The reaction is exothermic. After 1 hour stirring at 20° the mixture is fractionally distilled. There is obtained ethyl 2-cyanoethyl(phenyl)phosphinate as a colorless oil, b.p. 134°-136°/7 Pa.
