Эти соединени до насто щего времени практически не изучены изза их труднодоступности. В то же врем они представл ют интерес дл изучени в качестве физиологически активных веществ, полупродуктов синтеза и т.д.Until now, these compounds have not been practically studied because of their inaccessibility. At the same time, they are of interest for studying as physiologically active substances, semi-synthetic products, etc.
Известен способ получени пре ставителей 0-арилметил(этил)-1окси-2 ,2,2-трлхдорэтилфосфинатов конденсациай хлорал с 0-арилметил (этил)фосфонитами. Однако исходные фосфониты труднодоступны.A known method for producing representatives of 0-arylmethyl (ethyl) -1oxy-2, 2,2-trlhdorethylphosphinates condensate chloral with 0-arylmethyl (ethyl) phosphonites. However, the original phosphonites are difficult to access.
Целью изобретени вл етс упрощение процесса.The aim of the invention is to simplify the process.
Предлагаемый способ получени The proposed method of obtaining
i 0-ар л-1-окси-2,2,2-трихлорэтилфосфинатов на основе производных трехвалентного фосфора заключаетс в том, что 0-арилхлорфосфониты подвергают взаимодействию с хлоральгидратом .i 0-ar l-1-hydroxy-2,2,2-trichloroethyl phosphinates based on derivatives of trivalent phosphorus consist in the fact that 0-aryl chlorophosphonites are reacted with chloral hydrate.

в качестве О-арилхлорфосфонита можно использовать также продукт взаимодействи эквимол рных количеств дихлорфосфина и фенола в присутствии третичного амина, например триэтилалшна, в органическом растворителе, например хлороформе или бензоле.as O-arylchlorophosphonite, it is also possible to use the product of the interaction of equimolar amounts of dichlorophosphine and phenol in the presence of a tertiary amine, for example triethyl, in an organic solvent, for example chloroform or benzene.
Конечные продукты получают с хорошим выходом (Ь1-95) и выдел ют обычными приемами. Они представл : ЮТ собой кристалли 1 ческие вещества или в зкие жидкости, хорошо раствоThe final products are obtained in good yield (L1-95) and are isolated by conventional methods. They are: UT are crystalline substances or viscous liquids, well dissolved
