Cleavage of perfluoroisobutylene oxide by perfluoroalkoxy anions

Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    The cleavage of perfluoroisobutylene oxide by the anions that are generated from perfluorocarbonyl compounds and alkali metal fluorides gave the acid fluorides ofα-perfluoroalkoxyperfluoroisobutyric acids.

  2. 2.

    Perfluoroisobutylene oxide in diglyme, in the presence of cesium fluoride, is dimerized to the acid fluoride ofα-perfluoroisobutoxyperfluoroisobutyric acid.

  3. 3.

    Decarboxylation, with the formation of 2-hydro-2-perfluoroalkoxyperfluoropropanes, occurs when the acid fluorides ofα-perfluoroalkoxyperfluoroisobutyric acids are saponified.

  4. 4.

    Difluorephosgene is cleaved, with the formation of 2-perfluoroalkoxyperfluoropropylenes, when the acid fluorides ofα-perfluoroalkoxyperfluoroisobutyric acids are heated over Na2CO3.
