Yield:813-77-4 90%
Reaction Conditions:
with trichlorophosphate at -10 - -5; for 2 h;
Steps:
15.1 First step reaction: Preparation of oxy, oxy-dimethylphosphoryl chloride:
Put 7.6g (0.05mol) of phosphorus oxychloride into a three-neck bottle,Stir cold to -10 °C. Slowly add 3.2 g (0.1 mol) of methanol,The temperature was controlled at -5 ° C and the addition was carried out for 1 h.Stirring was continued for 1 hour. The reaction was added to 0 ° C cold water for washing,Layered, the lower layer is dichloride.Cool to -10 °C.10.0 g (0.1 mol) of potassium hydrogencarbonate was added in portions to the dichloride.The temperature was maintained at -5 °C. After the addition, wash with 1% hydrochloric acid water,The mixture was allowed to stand for stratification, and the lower layer was taken to obtain a product of 6.5 g, and the yield was 90%.
