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
