Abstract:
1. 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 %: 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 R X is a halogen atom.
