Document Type and Number:
WIPO Patent Application WO/2007/148597
Kind Code:
A1
Abstract:
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,
