Methyl Chloride → Dimethyl allylphosphonate

참여 물질

반응 단계

124 parts of trimethyl phosphite, together with 1 part of Raney nickel, are heated for 1 hour to 130°-140° C in a nitrogen atmosphere. 80 parts of allyl chloride are then slowly added dropwise so that the temperature does not fall below 80° to 90° C. The methyl chloride formed escapes through the reflux condenser. The reaction is over after 22 hours. The Raney nickel is filtered off, followed by fractionation in vacuo. Bp: 83°-84° C/12 Torr; nD20 : 1.4371; Yield: 86 parts, corresponding to 57% of the theoretical.
