Reaction of aliphatic primaryamines with alkyl α-H-perfluoroesters led to the corresponding β-iminoester as the major or the unique tautomer, depending on the length of the perfluoroalkyl chain.
Selectivity in the synthesis of fluorinated heterocycles from αβ-unsaturated perfluoroacyl derivatives (or their synthetic equivalents) and 1,2-bis-nucleophiles
Reactions of vicinal diamines, aminoalcohols, aminothiols with synthetic equivalents of perfluoroenones 3 or alpha,beta-unsaturated perfluoroesters 6 gave regiospecifically new five member (imidazo or oxazolidines) or seven member fluorinated heterocycles (dia or thiazepines).

The title compounds were synthesized in a high yield one pot procedure from alpha-H-perfluoroesters and aliphatic amines. From primary amines, the beta-imino tautomer was shown to be more stable than the enamino one, which is only observed with butanoic derivatives, as a minor component. The reaction did not occur with aromatic amines. In the propanoic series, the reaction product was the beta-amido-alpha-fluoroester.
