Известен способ получени алкоксизамещенных виниловых зфиров кислот п тивалентного фосфора, содержащих в концевой мегиленовой группе электроноакцепторные заместители, который заключаетс , в том, что производные кислот трехвалентного фосфора, имеющие хот бы одну алкоксигруппу, подвергают взаимодействию с эфирами галоидсодержащих карбоновых кислот.A known method for producing alkoxy-substituted vinyl esters of pivalent phosphorus containing electron-withdrawing substituents in the terminal megylene group, which consists in that derivatives of trivalent phosphorus acids having at least one alkoxy group, is reacted with halo-containing carboxylic acid esters.
Однако способ получени соединений указанной формулы в литературе не описан и вл етс новым.However, the method for preparing compounds of this formula is not described in the literature and is new.
Моно-а-алкоксизамещенные винштовые зфиры кислот п тивалентного фосфора могут найти применение в качестве присадок к полимерным материалам, а также в качестве полупродуктов дл синтеза соединений, обладающих инсектицидным действием. Кроме того, в отличие от ранее известных соединений подобной структуры соединени предлагаемой формулы вл ютс м гкими фосфорилирующими реагентами, что обусловлено наличием незамещенной концевой метиленовой группы.Mono-a-alkoxy-substituted screw derivatives of pyvalent phosphorus acids can be used as additives for polymeric materials, as well as intermediates for the synthesis of compounds with insecticidal action. In addition, unlike previously known compounds of a similar structure, the compounds of the proposed formula are soft phosphorylating reagents, due to the presence of an unsubstituted terminal methylene group.
Способ получени моно-а-алкоксизамещенных виниловых зфиров кислот п тивалентного фосфора , согласно изобретению, заключаетс в том что натриевые енол ты зфиров уксусной кислоты подвергают взаимодействию с моногалоидангидридами кислот п тивалентного фосфора в среде органического растворител в атмосфере инертного газа при охлаждении, желательно до температуры минус 70 -- минус 75 С. . Целевые.продукты выдел ют известными приемами.The method for producing mono-a-alkoxy-substituted valence acids of pyvalent phosphorus, according to the invention, is that sodium enolates of acetic acid gels are reacted with monohalohydrides of acids of pyruvic phosphorus in an organic solvent medium in an inert gas atmosphere during cooling, preferably to a temperature of minus 70 - minus 75 S. Target products are isolated by known techniques.
Полученные соединени устойчивы, перего«аютс без разложени при уменьшенном давThe compounds obtained are stable, stable without decomposition under reduced pressure.
