The Synthesis of the Fluorinated Ethers Perfluoroglyme and Perfluorodiglyme by Direct Fluorination.

摘要

The synthesis of perfluorinated ethers and polyethers using existing technology is often difficult and in many cases impossible to accomplish. A facile general synthesis with possible commercial importance has been developed in our laboratory by employing Modivied LaMar direct fluorination techniques. Perfluorinated polyethers are of interest as potential high stability fluids and as solvents. Of the reported products, only 'perfluoroglyme' (perfluoro-1,2-dimethoxyethane) has been prepared in 4% yield based on the electrolytic fluorination and cleavage of 1,4-dioxane. (Author)
