Imidazolium based Ionic Liquids (IL) and salts find application in a wide variety of fields including catalysis and advanced materials. We report here the reaction of 1,3-dimethylimidazolium-2-carboxylate with dimethylcarbonate (DMC) at temperatures ranging from 180 to 200 °C to yield 2-ethyl-1,3-dimethylimidazolium methyl carbonate salt (yield of 75 %).The 1,3-dimethylimidazolium-2-carboxylate /dimethylcarbonate reaction system has been employed in the synthesis of 1,7-heptanedioic acid dimethyl ester from cyclohexanone and DMC.
