Catalytic process for making hydrofluoroethers

Briefly, in one aspect, this invention provides a catalytic method of preparation of primary and secondary hydrofluoroethers, the process comprising reacting a fluorinated precursor material and an alkylating agent in the presence of a Lewis acid catalyst or a mixture comprising Lewis acid and Bronsted acid catalysts.

Electrochemical fluorination of N-containing carboxylic acids: Part 5. Fluorination of the methyl esters of cis-2,6-dimethylmorpholino-group substituted carboxylic acids

Cis-2,6-dimethylmorpholine and its derivatives having an ester group were subjected to electrochemical fluorination. The electrochemical fluorination of cis-2,6-dimethylmorpholine afforded only a small quantity of F-(N-fluoro-2,6-dimethyl-morpholine), whereas the N-(meth-oxycarbonylalkyl)-substituted cis-2,6-dimethyl-morpholines gave the corresponding F-acid fluorides in fair yields. Cis-and trans-isomerization on two methyl substituents of the morpholine ring occurred through electrochemical fluorination of pure cis-2,6-dimethylmorpholine to give a 1:0.25-0.5 mixture of cis- and trans-isomers having a F-2,6-dimethylmorpholino-moiety. The formation of a seven-membered ring expanded product was confirmed as a by-product in the fluorination of methyl cis-2,6-dimethylmorpholino-acetate. Spectroscopic data as well as physical properties of new nitrogen-containing F-carboxylic acids are presented.
