Fluorinations of the free-radical adducts of fluorinated alkenes, to ethers, overcobalttrifluoride are described and perfluorinated ethers are obtained at temperatures in excess of 400°C. The effect of structure on the formation of perfluoroethers is outlined.

Free-radical additions of hexafluoropropene to cyclic ethers may be carried out to achieve mono- or di-adducts and mixtures of isomers of di-adducts are formed. These adducts may be fluorinated, using electrochemical fluorination, to give the corresponding perfluoro-ethers and, in some cases, with surprising efficiency. Adducts of acyclic ethers are less efficiently fluorinated.
