Interaction of hexafluoropropene trimers with ammonia and primary amines

Abstract

Hexafluoropropene trimers (HFPT) react with primary amines to form the corresponding enamines and enimines, i.e. products arising from the indirect substitution of fluorine atoms. The adduct with HFPT has been obtained for the first time in the reaction with ammonia. The intramolecular cyclization of the compounds synthesized to give azetines and azetidines has been studied. Specific features of the 19F NMR spectra of the enimines obtained have been considered.
