発明の概要(英語) (US7635780)
A production method of fluorinated compounds, for producing a compound represented by formula (3) in a fluorine-based solution in a flow of fluorine gas after reaction of at least one type of compounds represented by formula (1) and at least one type of compounds represented by formula (2).
Similarly, fluorinated compounds represented by formula (4) prepared by the fluorination of compounds obtained by the reaction of formula (1) and formula (2)'.
The fluorinated polymers obtained by the polymerizations of formula (3) and (4) compounds are useful as an optical or electrical materials. wherein R1, R2, R3, R4, Rff1, Rff2, Rff3, Rff4, X, Y, Z, and n are defined in the specification respectively.
特許請求の範囲(英語) [claim1]
1. A method for producing a fluorinated compound represented by the following formula (3), the method comprising a step of fluorinating, in a fluorine-based solution under a fluorine gas atmosphere, a compound obtained by reacting at least one compound represented by the following formula (1) and at least one compound represented by the following formula (2):
wherein in formula (1), X represents a hydrogen atom or a fluorine atom, and Y represents an alkyl group having 1 to 7 carbon atoms or a polyfluoroalkyl group having 1 to 7 carbon atoms; and in formula (2), Z represents a hydroxyl group, a chlorine atom, or a bromine atom, and R1 to R4 each independently represent a hydrogen atom, an alkyl group having 1 to 7 carbon atoms, or a polyfluoroalkyl group having 1 to 7 carbon atoms
wherein, in formula (3), Rff1 to Rff4 each independently represent a fluorine atom or a perfluoroalkyl group having 1 to 7 carbon atoms.
[claim2]
2. The method for producing a fluorinated compound according to claim 1, wherein the fluorine gas atmosphere is a mixed atmosphere of nitrogen gas and fluorine gas, and the proportion of the nitrogen gas with respect to the fluorine gas is in a range from 2 to 4.
[claim3]
3. The method for producing a fluorinated compound according to claim 1, wherein, in the step of fluorinating, a reaction temperature is kept in a range of 0 to 5 deg. C., and stirring is carried out.
