摘要

This research paper presents a comprehensive study of the development, fabrication, and analysis of a novel surfactant-based task-specific ionic liquid (TSIL, cetyltrimethylammoniumprolinate [CTA][Pro]), which possesses versatile abilities as a phase-transfer catalyst, ligand, and reducing agent. The IL [CTA][Pro] exhibited high activity and recyclability in the palladium-catalyzed Mizoroki–Heck (MH) cross-coupling reaction of various haloarenes with olefins to generate cross-coupling products with excellent yields, in the presence of palladium chloride under aqueous phosphine-free conditions. Notably, both palladium and [CTA][Pro] can be reused for up to 6 consecutive cycles without significant loss of catalytic performance, reflecting the principles of green chemistry and the potential of these recyclable components in sustainable synthetic methodologies.
