Procedure

95 g of vinyldimethylphosphine oxide are dissolved in dioxane and rendered alkaline with sodium methoxide solution. 100 g of dimethyl phosphite are added dropwise, in an exothermic reaction. The mixture is then subjected to fractional distillation, which gives 104 g of product, boiling point at 0.4 mm Hg: 182° C. (yield: 53% of theoretical). The first runnings of the distillation contain unreacted dimethyl phosphite and vinyldimethylphosphine oxide, which can be used again in a further batch.
