Abstract:
The object is to provide a process for production of a compound having a fluorosulfonyl group and a novel compound. Thus, disclosed is a process for producing any one selected from the compounds (11) to (14) shown below. The process comprises the step of subjecting a compound: CXY=CHZ and a compound: Q(SO 2 F) m (C(O)OH) or a salt thereof to an electrode reaction (wherein symbols are as follows: X, Y and Z independently represent a group (A) selected from an alkyl group, a chloroalkyl group, a fluoroalkyl group, a hydroxyalkyl group, an alkoxycarbonyl group, a fluoroalkoxycarbonyl group, an alkylcarbonyloxy group and a fluoroalkylcarbonyloxy group each having 1-10 carbon atoms, a crboxyl group, a cyano group, or a chlorine, fluorine or hydrogen atom, provided that, when the group (A) contains an alkyl group moiety having 2 or more carbon atoms which may contain a fluorine atom, a group represented by the formula -O-, -C(O)-, -C(O)O- or -OC(O)- may be inserted between a carbon-carbon bond in the alkyl group; Q represents a polyfluoro saturated hydrocarbon group having 1-10 carbon atoms and has a valency of (m+1), provided that a group represented by the formula -O- may be inserted between a carbon-carbon bond in Q; and m represents 1, 2 or 3. Also disclosed is a compound (11 1 ), (11 2 ), (12 1 ), (12 2 ), (13 1 ) or (14 2 ) shown below, wherein R 1 represents a fluorine atom or a trifluoromethyl group; and Z 1 represents a hydrogen atom or a methyl group.
Abstract:
A fluoropolymer which is excellent in mechanical strength and transparency, has a high glass transition temperature which makes the polymer suitable for high-temperature use, and has a high refractive index. Also provided is a novel compound represented by the following formula (1). The fluoropolymer comprises monomer units (2) formed by the polymerization of the compound. In the formulae, R , R , R , and R each independently is fluorine, chlorine, a perfluorinated monovalent saturated hydrocarbon group, or perfluorinated (partially chlorinated, monovalent saturated hydrocarbon) group, provided that at least one of R , R , R , and R is perfluorinated (partially chlorinated, monovalent saturated hydrocarbon) group.
