Description
Оксиметильные фосфорорганические соединени с фторалкильными радикалами до насто щего времени не были известны.Oxymethyl organophosphorus compounds with fluoroalkyl radicals have hitherto not been known.
Предлагаемый способ заключаетс в том, что на метил-1, 1, 2, 2тетрафторэтилоксиметилфосфин действуют водным раствором перекиси водорода. Это позвол ет получить метил-1, 1, 2, 2-тетрафторэт локсиметилфосфина , что представл ет интерес дл синтеза негорючих полимеров.The proposed method consists in that methyl 1, 1, 2, 2 tetrafluoroethyl oxymethylphosphine is treated with an aqueous solution of hydrogen peroxide. This makes it possible to obtain methyl 1, 1, 2, 2-tetrafluoroethenoxymethylphosphine, which is of interest for the synthesis of noncombustible polymers.
Пример. В трехгорлую колбу, снабженную мешалкой, холодильником и капельной воронкой, внос т 5 г метил-1, 1, 2, 2-тетрафторэтилоксиметилфосфина . Затем при перемешивании небольшими порци ми приливают 1 г перекиси водорода в виде 6 %-ного водного раствора. Реакци сопровождаетс значительным выделением тепла. Путем охлаждени колбы температуру реакциопной смеси поддерживают равной О,Example. In a three-neck flask equipped with a stirrer, a condenser, and an addition funnel, 5 g of methyl 1, 1, 2, 2-tetrafluoroethyl oxymethylphosphine are introduced. Then, with stirring, 1 g of hydrogen peroxide is added in small portions in the form of a 6% aqueous solution. The reaction is accompanied by significant heat generation. By cooling the flask, the temperature of the reaction mixture is maintained at 0,
По окончании реакции удал ют воду под вакуумом, а остаток перегон ют в глубоком вакууме. Температура кипени 123°/1 мм.At the end of the reaction, water is removed under vacuum, and the residue is distilled under high vacuum. Boiling point: 123 ° / 1 mm.
Выход окиси метил-1, 1, 2, 2-тетрафторэтилоксиметилфосфина - 38 г (70% от теоретического, счита на метил-1, 1, 2, 2-тетрафторэтилоксиметилфосфИн ).The yield of methyl 1, 1, 2, 2-tetrafluoroethyloxymethylphosphine oxide is 38 g (70% of the theoretical value, calculated as methyl 1, 1, 2, 2-tetrafluoroethyl oxymethylphosphine).
Полученный продукт иредставл ет собой бесцветную жидкость, d2°4 - 1,5359, Пв20 - 1,4140.The resulting product is a colorless liquid, d2 ° 4-1.5359, P20: 1.4140.

Предмет изобретени Subject invention
Способ получени ок1иси 1метил-1, 1, 2, 2-тетрафторэтилоксиметилфосфина , отл и ч а ющи йс теМ;. что на метил-1, 1,2, 2-тетрафторэтилоксиметилфосфин действуют водным раствором перекиси водорода.The method of obtaining about 1methyl-1, 1, 2, 2-tetrafluoroethyloxymethylphosphine, excl. Tem ;. that methyl-1, 1,2, 2-tetrafluoroethyloxymethylphosphine is affected by an aqueous solution of hydrogen peroxide.
