Description
Взаимодействие полифторгалоидмеркаптанов с соединени ми, содержащими .подвижный атом водорода, привод щее к образованию различных производных полифторгалоидсодержэщих тионкарбоновых кислот в литературе не описано.The interaction of polyfluorohalo mercaptans with compounds containing a motile hydrogen atom, leading to the formation of various derivatives of polyfluorine halide containing thioncarboxylic acids, has not been described in the literature.
Предлагаетс способ получени полифторгалоидтионкарбоновых кислот и их производных, заключающийс в том, что полифторгалоидмеркаптан подвергают обработке веществами, несущими подвижный атом водорода. При этом образуютс следующие производные тионкарбоновых кислот: при обработке водой образуютс кислоты; при обработке спиртами (тиолами) -эфиры (тиоэфиры); при обработке вторичными аминами - амиды; при обработке слабыми карбоновыми кислотами - смещанные ангидриды.A method is proposed for the preparation of polyfluorohalide thionic carboxylic acids and their derivatives, which consists in the fact that polyfluorhydrohalide mercaptan is subjected to treatment with substances carrying a mobile hydrogen atom. The following thioncarboxylic acid derivatives are formed: when treated with water, acids are formed; when treated with alcohols (thiols) -ethers (thioesters); when processing secondary amines - amides; in the treatment of weak carboxylic acids - offset anhydrides.
В общем виде реакци описываетс следующим уравнением: R/ - CF, - SHг.- R - С , гдеIn general, the reaction is described by the following equation: R / - CF, - SHg. - R - C, where

Пример: Получение фторхлортионуксусной кислоты 7 г (0,046 г-мол) 2,2-фторхлор-1,1-дифторэтилмеркаптана обрабатывают 18 г (1,0 г-мол) воды при интенсивном перемещивании и охлаждении в стекл нном реакторе. Реакционную массу выдерживают при температуре 70° в течение 30 мин, затем масл нистую жидкость отдел ют отExample: Preparation of Fluorochlorothionoacetic Acid 7 g (0.046 gmol) of 2,2-fluorochloro-1,1-difluoroethyl mercaptan is treated with 18 g (1.0 gmol) of water with intensive transfer and cooling in a glass reactor. The reaction mass is maintained at a temperature of 70 ° for 30 minutes, then the oily liquid is separated from
