Surface active ionic liquid assisted metal-free electrocatalytic-carboxylation in aqueous phase: a sustainable approach for CO₂ utilization paired with electro-detoxification of halocarbons

Abstract

Electrocarboxylation of halocarbons in aqueous micellar solutions of Imidazolium based surface active ionic liquids offers a promising green strategy for capture, fixation and utilization of CO2 for the synthesis of high-added value compounds.

Ionic Liquids in Metal, Photo-, Electro-, and (Bio) Catalysis

“…In the years following these two reports, only a few articles have been published, most of which deal with the incorporation of CO 2 into organic molecules. The reactions identified include aromatic ketone electrocarboxylation, − electrochemical CO 2 cycloaddition to epoxides, ,, electrocarboxylation of acyl halides, electrosynthesis of dialkyl carbonates from alcohols, CO 2 , and alkyl iodides, − electrosynthesis of carbamates using amines, , electrocarboxylation of alkyl or aryl halides, − and olefin electrocarboxylation . In several cases, the organic electrosynthesis performed with IL electrolytes does not involve the direct reduction of CO 2 to the anion radical.…”

Quantitative Relation between Ionic Diffusivity and Ionic Association in Ionic Liquid–Water Mixtures

“…Ionic liquids (ILs) are fluids composed entirely of cations and anions, which are well-known as a promising green solvent/electrolyte in many fields due to their excellent physicochemical properties such as high thermal stability, wide electrochemical potential window, negligible vaporization, and nonflammability. − However, the applications often suffer from high viscosities of ILs compared to conventional solvents, which can lead to slow mass transfer processes, for example, low ionic conductivities in energy storage devices of ILs. One common approach to improve ionic transport is to mix the IL with another low-viscosity solvent, for example, water, which is cheap, safe, and environmentally friendly.…”

“…One common approach to improve ionic transport is to mix the IL with another low-viscosity solvent, for example, water, which is cheap, safe, and environmentally friendly. Recently, IL–water mixtures have gained great attention owing to their application potential in biological techniques, , electrochemistry, , and extraction . Therefore, a better understanding of the behaviors of ILs in their aqueous mixtures is desired to guide prediction, control, and design in these applications.…”
