    摘要： Trifluoromethyl compounds of the formulas ##EQU1## are useful as oil repellants. Substituted barbituric acid derivatives thereof of the formula ##EQU2## are useful as central nervous system depressants for animals. Trifluoromethylfluorocarbonylketene and trifluoromethylmalonyl fluoride are prepared by reacting perfluoromethylacryloyl fluoride with a carboxylic acid.

The compounds can be polymerized by opening of the oxetane ring in the presence of electrophilic agents, or the oxetane ring can be hydrolyzed to a dihydroxy group and reacted with diacid halides to form polyesters or with diisocyanates to form polyurethanes. Both monomers and polymers complex metal ions and can be used to separate such ions from solutions.
