Abstract:
A process for producing a fluorine-containing compound, which comprises:reacting compound (I) with compound (II) to form compound (III) having a fluorine content ranging from 30-76% by wt; fluorinating compound (III) in a liquid phase to form compound (IV); and converting compound (IV) to compound (V), compound (VI) or a combination of compounds (V) and (VI): RAâ€”E1 (I) RBâ€”E2 (II) RAâ€”E-RB (III) RAFâ€”EF-RBF (IV) RAFâ€”EF1 (V) RBFâ€”EF2 (VI) â€ƒwherein RA, RB: 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 RHF by a fluorination reaction in a liquid phase, RHF: 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 saturated hydrocarbon) group, substituted by a fluorine atom; RAF, RBF: RAF is a group corresponding to RA, and RBF is a group corresponding to RB; and in the instance where each of RA and RB 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 monovalent saturated hydrocarbon) group, RAF and RBF are the same groups as RA and RB, respectively, or are RA and RB groups each substituted by at least one fluorine atom, and in the case where RA and RB are monovalent organic groups (RH), RAF and RBF are RHF, respectively; E1, E2: reactive groups which are mutually reactive to form a bivalent connecting group (E); E: a bivalent connecting group formed by the reaction of E1 and E2; EF: the same group as E, or a group in which E is fluorinated, provided that at least one of RAF, RBF and EF, is not the same group as the corresponding RA, RB and E, respectively; EF1, EF2: each independently is a group formed by dissociation of EF.
