Abstract
Room-temperature ionic liquids have become a widely used alternative to conventional molecular organic solvents as a reaction medium. Few preparations of ionic liquids provide efficient access to these solvents; furthermore, none is fully adaptable to an undergraduate organic chemistry laboratory. In this article, several imidazolium-based ionic liquids are formed in facile and efficient one-pot procedures using water or ethanol as a solvent. These reactions are suited for a four-hour organic chemistry laboratory without special equipment.

 Caution! 
Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations.
