Fluorinated ethers. Communication 3. Preparation of fluorinated ethers by addition of alcohols to epoxides, interaction of fluoroolefins and alcohols with formaldehyde, transesterification, electrochemical fluorination and a number of other methods.

The following methods of obtaining fluorinated ethers are described in the final part of the review: the addition of alcohols to epoxides, the interaction of fluorinated olefins and alcohols with formaldehyde, transetherification, and electrochemical fluorination. In addition, a brief description of methods for obtaining fluorinated ethers that are not included in the separate chapters is given, namely: free radical addition of fluorine-containing alkenes to ethers, fluorination with elemental fluorine and higher fluorides of metals of variable valence, reactions of alcohols with ketones and carboxylic acids, reactions of perfluorinated nitrosoalkanes with alcohols and interaction of alcohols with 2,4,6-tris-(2,2,2-trifluoroethoxy)-[1,3,5]triazine (TriTFET).
