ABSTRACT:
The present invention relates to producing a disulfonyl fluoride compound easily and efficiently by utilizing coupling reaction where a compound (2) is obtained by subjecting a compound (1) wherein Y is a fluorine atom to photocoupling reaction, or subjecting a compound (1) wherein Y is a hydroxyl group, —OMawherein Mais an alkali metal atom, or —O(Mb)1/2wherein Mbis an alkaline earth metal atom to electrolytic coupling reaction, and derivatives such as the following compound (7A) are obtained from the compound (2):in-line-formulae description="In-line Formulae" end="lead"?FSO2-E-CX2—COY (1)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?FSO2-E-CX2—CX2-E-SO2F (2)in-line-formulae description="In-line Formulae" end="tail"?wherein E is a single bond, —O—, a C1-20alkylene group which may contain an etheric oxygen atom, or the like, X is a fluorine atom or the like, and Y is a fluorine atom, a hydroxyl group, or the like.
