Advances in Functionalized Ionic Liquids as Reagents and Scavengers in Organic Synthesis

Abstract

Functionalized ionic liquids (FILs) synthesized with specific desired chemical properties have shown promising results in various areas of organic synthesis. In supported organic synthesis, FILs have become known as a new alternative to commonly used PEG and fluorous soluble supports. This review summarizes the progress of recent development in the synthesis of functionalized ionic liquids with emphasis on their applications as reagents and scavengers in organic synthesis.

From Conventional Lewis Acids to Heterogeneous Montmorillonite K10: Eco‐Friendly Plant‐Based Catalysts Used as Green Lewis Acids

“…For more than ten years now, alternative methods have been developed and evolved in agreement with the green chemistry concept. The aims of these methods were to 1) develop Lewis acid catalyzed reactions in supercritical fluids, such as supercritical CO 2 or supercritical water; and 2) create an alternative reaction medium to volatile organic solvent by using ionic liquids . The great advantages of using these liquids are their nonflammability, high chemical and thermal stability, conductivity and polarity, negligible vapor pressures, ability to solvate solutes, miscibility with organic solvents and water, and their recycling processes.…”

On the Anion Exchange of PX3 (X = Cl, Br, I) in Ionic Liquids comprising Halide Anions

“…Owing to their distinctive physical properties, such as a wide temperature range of the liquid phase, high redox and thermal stability, negligible vapor pressure, and tuneable polarity, ILs are discussed as solvents for various fields of applications. They can be used, e.g., in separation techniques, electrochemistry, catalysis, organic synthesis,, processing of biomass, and in the synthesis of inorganic materials , . Thus, the replacement of conventional solvents with ILs seems to be feasible and in many cases advantageous.…”
