Reaction Steps

To a solution of 270 ml of phenyldichlorophosphine in 1000 ml of diethylether is added with stirring and cooling with ice a solution of 280 ml of ethanol and 280 ml of triethylamine in 500 ml of diethylether. After stirring for 14 hours at 20° the precipitate is filtered off and the filtrate is fractionally distilled. There is obtained phenylphosphonous acid-ethylester as a colorless liquid, b.p. 83-85°/6 Pa.
