Utilizing previously reported synthetic protocols for the halide- and metal-free synthesis of organic salts, we have prepared a new group of imidazolium and pyrrolidinium azolate anion-based salts demonstrating the general applicability of the methodology and expanding our investigation into non ion exchange routes to potentially energetic ionic liquids. Eighteen salts, out of which six exhibit melting points below 100 °C, were prepared by a simple decarboxylation reaction, which resulted in clean formation of the new compounds without the need for extensive purification. The low stability of the H 2 CO 3 by-product, and its decomposition to CO 2 and H 2 O in aqueous media, allows for purification of the salts by evaporation only. Eighteen azolium azolate salts were prepared by a simple decarboxylation reaction.
