    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.)

    摘要: Compounds of formula (1), wherein: R?1 and R2¿ are independently selected from the group comprising hydrogen, C¿1? to C6 alkyl, C1 to C6 haloalkyl, phenyl, and substituted phenyl; X is selected from the group comprising sulfur, sulphone, disulfide; Y is selected from oxygen, carbon, N-H, N-alkyl, N-aryl, or sulfur; and Z is any linking functionality. The compounds represent a new class of ring opening monomers.
