Conventionally, ionic liquids with anions generated from simple organic acids are prepared following a metathetic procedure from a halide salt, usually a chloride. Here, we describe an efficient means of generating hydroxide solutions of the cations of interest, allowing many ionic liquids to be produced by simple acid-base reactions, completely avoiding the use of halides.
