Patent ID: 6951957

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 in a liquid phase to form compound (IVd); and then converting compound (IVd) to compound (Ve) and/or compound (VIf), wherein the molecular weight of compound (Ia) ranges from 50 to 200, and the molecular weight of compound (IIIc) ranges from 200 to 1000: 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 (RH) 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.
