Abstract

1, 3-Dialkylimidazolium-2-carboxylate compounds of formulas 1a, 2, and 4 have been synthesized and fully characterized by X-ray spectroscopy quite recently. Up today, these compounds have found some interesting applications as precursors of N-heterocyclic carbenes (NHCs) used as ligands for metal-complexes or in the synthesis of organic compounds and ionic liquids. We have recently reported the use of 1-butyl, 3- ...
