Patent ID: 7635780

Claim:
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 R 1 to R 4 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), R ff 1 to R ff 4 each independently represent a fluorine atom or a perfluoroalkyl group having 1 to 7 carbon atoms.
