Polyfluorinated oxetanes are prepared in high yields by an electrophilic [2 + 2] cycloaddition reaction between hexafluoroacetone and fluorinated ethylenes that is catalyzed by an anhydrous aluminum chlorofluoride Lewis acid. The reaction is regiospecific with hydrofluoroethylenes CHX=CF2(X=H, F, Cl, Br), whereas halotrifluoroethylenes CFX=CF2 (X=Cl, Br) give nearly equal amounts of the isomeric oxetanes. Hexafluoropropylene oxide, which rapidly rearranges under the reaction conditions, can be substituted for hexafluoroacetone in this new oxetane synthesis.
