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.

A new ‘one pot’ synthesis of 2-hydro-3-oxo-perfluoroesters from 2-hydroperfluoroesters is reported. These compounds have a great tendency to hydrate. The hydrate, the keto and enol forms of the anhydrous compound have been characterized. A remarkable 4J coupling between the enolic proton and fluorine is observed. The keto-enol equilibrium was determined and the enol ratio found to be greatly decreased

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.
