N-Substituted trifluoroacetimidoyl halides in ionic-type transformations readily undergo nucleophilic substitution and dehydrofluorination rather than 1,3-dehydrohalogenation to give nitrile ylides.

Defluorination of polyfluorinated acylimines by zinc on heating in dioxane gave polyfluorinated oxazoles. The behavior of polyfluorinated oxazoles in nucleophilic substitution was studied.
