FIELD: organic chemistry. SUBSTANCE: desired product 1-methoxy-3-methyl-3-phospholene oxide has essential formula C6H11O2P, its boiling point being 75-79 C. 1,3-diene is used as reagent 1, trihalide of phosphorous is used as reagent 2. Their interaction is carried out in inert atmosphere in the presence of inhibitor of polymerization. Thus prepared product is activated with the help of chlorinated hydrocarbons and by treatment with alcohols. Copper salt of fatty acid is used as mentioned above inhibitor of polymerization. Yield of desired product is 83.5 %. EFFECT: improves efficiency of the method. 7 cl
