This invention provides compounds of formula: in which Rf is a radical that carries a perfluoromethylene group, which group ensures bonding to the remainder of the molecule; R1 and R3, which can be the same or different, are chosen from among hydrogen and alkyl or aryl radicals; Ψ is an electroattractor group such that Ψ-O—H is an acid whose pKa (in water) is at most equal to 8, advantageously 6, and preferably 5. These compounds are useful for the synthesis of nitrogen-containing heterocyclic compounds.
