METHOD FOR PRODUCING CYCLIC DISULFONIC ACID ESTER

摘要

Disclosed is a commercially advantageous method for producing a cyclic disulfonic acid ester with high yield. Specifically disclosed is a method for producing a cyclic disulfonic acid ester represented by the general formula (3) below, which is characterized in that a silver alkanedisulfonate represented by the general formula (1) below and a dihaloalkane represented by the general formula (2) below are reacted in a nonpolar solvent.(1) (2) (3) (In the formulae, X₁ and X₂ independently represent a chlorine atom, a bromine atom or an iodine atom; and Y and Z independently represent a substituted or unsubstituted alkylene chain which may have a heteroatom in the chain.)
