摘要:
                                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.
