Abstract

Abstract The reaction of 1, 3-dimethylimidazolium-2-carboxylate and dimethylcarbonate (DMC) at high temperature yielded the new compounds 2-ethyl-1, 3-dimethylimidazolium methyl carbonate salt and 2-ethyl-1, 3-dimethylimidazolium-4-carboxylate zwitterion which were obtained as a mixture in approximately 4: 1 molar ratio. The compounds were also isolated in pure form through alternative synthetic procedures and characterized by ESI- ...
