Used as an ionic liquid in organic synthesis and catalysis due to its ability to stabilize reactive intermediates and enhance reaction rates. Commonly employed as a solvent or catalyst support in cross-coupling reactions, such as Heck and Suzuki reactions. Its allyl group allows for further functionalization or polymerization, making it useful in the preparation of task-specific ionic liquids and polymeric materials. Also applied in electrochemistry and as a phase-transfer catalyst in biphasic systems. Shows promise in green chemistry applications by enabling milder reaction conditions and recyclable reaction media.
