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.

Keywords: barium; green synthesis; ionic liquids; metathesis; strontium
