| description | The invention discloses a preparation method of methylene phosphorus dichloride, which comprises the following steps: in the presence of an organic solvent, taking a compound 1 as a substrate, carrying out cleavage reaction on the compound 1 under the action of trimethylhalosilane to generate an intermediate product, and carrying out chlorination reaction on the intermediate product and a chlorination reagent to finally generate the product methylene phosphorus dichloride. Compared with the prior art, the method provided by the invention has the advantages of easily available raw materials, low cost, high yield, mild reaction conditions and lower danger coefficient, and is beneficial to large-scale industrial production.
本发明公开一种亚甲基双氯化磷的制备方法：在有机溶剂存在下，以化合物1作为底物，所述化合物1在三甲基卤硅烷的作用下，发生裂解反应，生成中间产物，所述中间产物再与氯代试剂发生氯代反应，最终生成产物亚甲基双氯化磷。相比现有技术，本发明提供的方法原料易得，低成本高收率，同时反应条件温和，危险系数较低，有利于规模化工业生产。 |
