Patent ID: 7083705

Claim:
A process for producing a fluorine-containing compound, which comprises: reacting compound (Ia) with compound (IIb) to form compound (IIIc); fluorinating compound (IIIc) with fluorine gas in a liquid phase to form compound (IVd) by one of the following two methods: i) reacting compound (IIIc) with fluorine gas in a solvent medium in the presence of a C—H bond containing compound, or ii) reacting compound (IIIc) with fluorine gas in a solvent medium with exposure to UV radiation; and then converting compound (IVd) to compound (Ve) and/or compound (VIf), wherein the fluorine content in compound (Ia) is less than 10 wt %, and the fluorine content in compound (IIIc) ranges from 30 to 76 wt %: R A CH 2 OH (Ia) XCOR B (IIb) R A CH 2 OCOR B (IIIc) R AF CF 2 OCOR BF (IVd) R AF COF (Ve) R BF COF (VIf) wherein R A , R B : each independently is a monovalent saturated hydrocarbon group, a halogeno-monovalent saturated hydrocarbon group, a hetero atom-containing monovalent saturated hydrocarbon group, a halogeno (hetero atom-containing monovalent saturated hydrocarbon) group, or a monovalent organic group (R H ) which can be converted to R HF by a fluorination reaction in a liquid phase, R HF is a group having at least one hydrogen atom in a group selected from the group consisting of a monovalent saturated hydrocarbon group, a partially halogeno-monovalent saturated hydrocarbon group, a hetero atom-containing monovalent saturated hydrocarbon group, and a partially halogeno-(hetero atom-containing monovalent hydrocarbon) group, substituted by a fluorine atom; R AF , R BF : R AF is a group corresponding to R A , and R BF is a group corresponding to R B ; and in the instance where each of R A and R B is a monovalent saturated hydrocarbon group, a halogeno monovalent saturated hydrocarbon group, a hetero atom-containing monovalent saturated hydrocarbon group, or a halogeno (hetero atom-containing saturated hydrocarbon) group, R AF and R BF are the same groups as R A and R B , respectively, or groups having at least one hydrogen atom present in the groups of R A and R B substituted by a fluorine atom, and in the case where R A and R B are monovalent organic groups (R H ), R AF and R BF are R HF , respectively; and X is a halogen atom.
