Three in a row : We report i) the successful halide‐free, efficient syntheses of azolium azolates by reaction of 1,3‐dimethylimidazolium‐2‐carboxylate with neutral azoles (by a one‐pot synthesis with an easy to remove byproduct (CO 2 gas, see scheme), ii) the development of a facile, low sample demand method for ready determination of the eutectic point compositions of mixtures of these salts, and iii) the application of the new synthetic techniques for the direct preparation of the eutectic mixtures.
