Abstract:: ... A series of new 1-butylimidazole-based ionic liquids (3a–h) have been synthesised by the quaternisation reaction of 1-butylimidazole with different alkyl- and alkoxy-substituted aryl halides using a microwave solvent-free approach with ≈82–95% yield. The solvent-free approach allows the preparation of a variety of ILs with better yields and purities, making any further purification unnecessary. Th ...
