摘要：
It is an object of the present invention to provide a commercially advantageous method for producing a cyclic disulfonic acid ester with high yield, the present invention discloses a method for producing a cyclic disulfonic acid ester represented by the general formula (3), which comprises reacting a silver alkanedisulfonate represented by the general formula (1) with a dihaloalkane represented by the general formula (2) in a nonpolar solvent.
Wherein X 1 and X 2 are each independently a chlorine atom, a bromine atom or an iodine atom; and Y and Z are each independently a substituted or unsubstituted alkylene chain which may have a heteroatom in the chain.
