Abstract:

Sulfur-based heterocycles are essential structural motifs in pharmaceuticals, agrochemicals, and advanced materials. However, conventional synthetic methods often involve hazardous reagents and environmentally unfriendly solvents. Ionic liquids (ILs) have emerged as sustainable alternatives due to their unique physicochemical properties, including negligible vapor pressure, high thermal stability, and tunable polarity.

This paper reviews emerging techniques for synthesizing sulfur-containing heterocycles using ionic liquids, focusing on multicomponent reactions, task-specific ionic liquids, C–H functionalization, and nanoparticle-assisted catalysis. Recent developments (2024–2026) demonstrate that ILs enhance reaction efficiency, selectivity, and sustainability. Mechanistic insights, green chemistry aspects, and future research directions are also discussed.
