Procedure

A mixture of 24.7 g of isopropanol and 17.2 g of triethylamine in 35 ml of diethylether is added drop by drop to 30 g of t-butyldichlorophosphine in 100 ml diethylether. The temperature is kept between 5° to 10°. The solid is filtered off and the filtrate evaporated. The crude oil is purified by distillation to yield t-butylphosphonous acid-isopropylester as an oil, b.p. 82°/2 kPa, nD20 =1.4222.
