With their ability to dissolve inorganic as well as organic materials, ionic liquids have emerged as a versatile solvent system for a diverse range of organic transformations. In the past few decades, the literature has witnessed remarkable advances in a wide range of organic conversions carried out in the presence of various imidazolium, pyridinium, pyrrolidinium, quinolinium and diazobicyclo-octane based ionic liquids. In the reaction, ionic liquids serve as a solvent, catalyst or sometimes both. In certain cases, they are also modified with metal nanoparticles or complexes to form heterogeneous catalysts or are immobilized onto solid support like agar-agar to act as solid-support catalysts. Reactions catalysed by ionic liquids incorporating chiral catalysts possess the advantageous features of being highly enantioselective and reproducible, besides being economical and easy to handle. In this review, an updated insight regarding the role played by ionic liquids in various C-C bond-forming organic reactions, has been summarized.

凭借其溶解无机和有机材料的能力，离子液体已成为用于多种有机转化的通用溶剂系统。在过去的几十年中，文献见证了在各种咪唑鎓，吡啶鎓，吡咯烷鎓，喹啉鎓和重氮二环辛烷值离子液体存在下进行的各种有机转化的显着进展。在反应中，离子液体充当溶剂，催化剂或有时兼用作两者。在某些情况下，它们还可以用金属纳米颗粒或配合物进行修饰以形成非均相催化剂，或固定在琼脂-琼脂等固体载体上以充当固体载体催化剂。掺有手性催化剂的离子液体催化的反应具有高对映选择性和可重现性的优点。除了经济且易于操作。在这篇综述中，总结了关于离子液体在各种形成CC键的有机反应中所起的作用的最新见解。
