Introduction

Imidazolium-Based Ionic Liquids

In 1982, room-temperature ionic liquids (ILs) based on 1,3-dialkylimidazolium salts with a tetrachloroaluminate anion were first reported [ 26] as shown in Fig. 1, and they are recognized as the first-generation ILs. In 1992, Wilkes and Zaworotko improved the air and water stability of imidazolium-based ILs (Im-ILs) by replacement of the moisture-sensitive anion by a tetrafluoroborate or other anions, resulting in the second-generation ILs [ 25]. These findings opened the door to numerous applications such as reaction media for various kinds of organic reactions. Task-specific ILs were proposed as the third-generation ILs [ 4].These Im-ILs have functional groups and are designed to have particular properties to achieve specific applications.
