Process for producing fluorinated compound
To provide a process for producing a desired perfluorinated product at a high yield in a fluorination reaction of a partially fluorinated ester. A perfluorinated compound (4) is obtained by fluorinating in a liquid phase a compound (3) (wherein the fluorine content is at least 30 mass %) obtained by reacting a compound (1) and a compound (2), wherein the compound (1) is HOCH.sub.2—R.sup.A—CH.sub.2OH, the compound (2) is X.sup.1C(═O)—C(R.sup.B)(R.sup.C)(R.sup.D), R.sup.A is a bivalent saturated hydrocarbon group or the like which has no hetero atom such as an etheric oxygen atom, X.sup.1 is a halogen atom, and —C(R.sup.B)(R.sup.C)(R.sup.D) is a branched group.
