1-Allyl-3-methylimidazolium iodide, CAS: 65039-07-8

Key Applications:

Catalysis and Organic Synthesis

• Functions as a versatile ionic medium for transition‑metal‑catalyzed reactions, particularly C–C and C–N bond‑forming transformations.
• Supports phase‑transfer catalysis where iodide enhances nucleophilicity and reaction rates.
• Useful in alkylation, substitution, and rearrangement reactions requiring a polar, thermally stable solvent.

Electrochemical and Redox Systems

• Serves as a conductive electrolyte in redox‑active systems, benefiting from the allyl group’s tunable electronic environment.
• Applied in electrochemical studies where iodide participates in charge‑transfer processes or acts as a redox shuttle.
• Suitable for electrodeposition environments requiring high ionic strength and low volatility.

Materials Science and Polymer Processing

• Employed as a solvent or co‑solvent for polymer dissolution, modification, and ion‑exchange processes.
• Supports the preparation of ionically functionalized polymers, membranes, and thin films.
• Useful in templating or directing the assembly of nanostructured materials due to its amphiphilic cation.

Photochemical and Light‑Driven Systems

• Utilized in dye‑sensitized and photoactive systems where iodide participates in electron‑transfer cycles.
• Can stabilize photoactive species in solution and facilitate regeneration pathways in sensitized materials.

Extraction, Separation, and Purification

• Effective in liquid–liquid extraction of metal ions, halides, and polar organics due to strong ion‑pairing with iodide.
• Applied in selective separations where the allyl‑substituted imidazolium cation provides enhanced solvation of unsaturated or aromatic species.

General Solvent and Processing Medium

• Provides a high‑polarity, low‑volatility environment for reactions sensitive to moisture or conventional organic solvents.
• Suitable for microwave‑assisted synthesis, enabling rapid heating and uniform energy distribution.
• Supports crystallization, dissolution, and stabilization of reactive intermediates.
