Solid potassium hydroxide dehydrofluorinates 2,2-bis-(trifluoromethyl)-3,4-difluoro-oxetan to 3-fluoro-4,4-bis-(trifluoromethyl)-2-oxete (59%), 2-pentafluoroethyl-3,4-difluoro-oxetan to 2-tetrafluoroethylidene-3,4-difluoro-oxetan, and -2-heptafluoro-n-propyl--3,-4-difluoro-oxetan to ()-2-hexafluoro-n-propylidene- -3,4-difluoro-oxetan. Factors which affect these reactions are discussed.
