1-Allyl-3-methylimidazolium dicyanamide, CAS: 917956-73-1

Key Applications:

1. Catalysis and Synthetic Chemistry

• Serves as a reaction medium for transition‑metal‑catalyzed transformations, including cross‑coupling, alkylation, and nucleophilic substitution.
• Supports homogeneous catalysis where high polarity and low coordinating interference are required.
• Facilitates enhanced reaction rates in systems benefiting from the dicyanamide anion’s weakly coordinating nature.

2. Polymer Science and Materials Processing

• Functions as a solvent or co‑solvent for polymerization of acrylates, methacrylates, and other vinyl monomers.
• Useful in ionically conductive polymer matrices and gel electrolytes due to its favorable ionic mobility.
• Applied in processing cellulose, chitin, and other biopolymers where strong hydrogen‑bond disruption is advantageous.

3. Electrochemical and Energy‑Related Applications

• Employed as an electrolyte component in supercapacitors and redox‑active systems requiring wide electrochemical windows.
• Supports electrodeposition processes for metals and alloys, benefiting from its low volatility and stable ionic environment.
• Investigated in dye‑sensitized and emerging photovoltaic systems as a conductive, low‑viscosity ionic medium.

4. Separation Science and Extraction

• Effective in liquid–liquid extraction of metal ions, particularly transition metals, due to the coordinating character of the dicyanamide anion.
• Utilized in selective extraction of organic compounds, including aromatics and nitrogen‑containing species.
• Suitable for supported ionic liquid membranes (SILMs) in gas separation and purification.

5. Thermal and Lubrication Systems

• Acts as a high‑temperature lubricant additive or base fluid where non‑flammability and thermal stability are required.
• Provides friction‑reducing and anti‑wear properties in specialized tribological environments.

6. Advanced Research and Formulation

• Used in the preparation of functionalized ionic liquids and polymerizable ionic liquid monomers via allyl‑based derivatization.
• Serves as a tunable medium for nanoparticle synthesis, enabling controlled nucleation and growth.
• Supports academic and industrial R&D exploring structure–property relationships in imidazolium ionic liquids.
