摘要： A process for producing a fluorine compound having a fluorosulfonyl group through a coupling reaction. The process, which is for producing a compound represented by the formula [(FSO 2 -) a (Z-) 3-a C-] n R(-COY) b-n , comprises reacting a compound represented by the formula (FSO 2 -) a (Z-) 3-a C(-COX) with a compound represented by the formula R(-COY) b by photocoupling reaction when X and Y each is fluorine or by electrolytic coupling reaction when X and Y each independently is hydroxy or a group represented by -OM. In the formulae, X and Y each is fluorine, hydroxy, or a group represented by -OM; Z is hydrogen, fluorine, chlorine, or a monovalent organic group; R is an organic group having a valence of b; M is an alkali metal atom, a is an integer of 1-3; and b and n each independently is an integer of 1-4, provided that b=n.

摘要： A method for producing a fluorine-containing alkyl ether is disclosed wherein a sufficient reaction rate can be attained even under mild conditions. This method enables to efficiently perform post-processes such as distillation following the reaction. After introducing a polar non-protic solvent, a fluorine-containing ether, a catalyst, a fluorine-containing alkyl alcohol and a fluorinated olefin into a reaction vessel, the fluorine-containing alkyl alcohol and the fluorinated olefin are reacted with each other so as to produce a fluorine-containing alkyl ether. In this method for producing a fluorine-containing alkyl ether, the mass ratio between the polar non-protic solvent and the fluorine-containing ether introduced in the reaction vessel (polar non-protic solvent/fluorine-containing ether) is from 5/95 to 80/20.
