Carbonylfluoride is a versatile intermediate to organic fluorine compounds. Its reaction with carbonyl compounds such as cyclohexanone, benzaldehyde and benzophenone gives the gem-difluorides, while N,N-dimethylformamide yields a,a-difluorotrimethylamine. Metal fluoride-catalyzed addition at the ethylenic bond in perfluoroolefins forms perfluoroacyl fluorides, while the C--?! unsaturated compounds

ethyl-phenylformamide 5 with sulphur tetrafluoride in the presence of potassium fluoride resulted in a direct conversion of the formyl group to the trifluoromethyl group to give excellent yields of dimethyl(trifluoromethyl)amine 2a, diethyl(trifluoromethyl )amine2b, 1-(trifluoromethyl)piperidine 4a, 4-(trifluoromethyl)morpholine 4b, and N-ethyl-N-(trifluoromethyl)aniline 6, respectively. The reaction

(Difluoroorganyl)dimethylamines, RCF2NMe2 (R = H, Ph, tBu), can be used as carbene precursors for phosphorus trifluoride in an oxidative addition reaction. By this method, complexes of sterically nondemanding asymmetric and acyclic carbenes were obtained that are otherwise not accessible.
