Abstract: Organosulfur heterocycles constitute an important class of compounds with wide applications in pharmaceuticals, agrochemicals, and materials science. Conventional synthesis often relies on toxic solvents and harsh conditions. Ionic liquids (ILs), recognized as green and tunable reaction media, have emerged as powerful alternatives. This paper reviews novel strategies employing ionic liquids for the synthesis of sulfur-containing heterocycles, focusing on mechanistic insights, catalytic efficiency, and sustainability. The integration of ILs as solvents, catalysts, and dual-function systems has significantly improved yields, selectivity, and recyclability, providing environmentally benign synthetic pathways.

This thesis explores novel strategies for synthesizing sulfur-containing heterocycles using ionic liquids as solvents, catalysts, and reaction media. Emphasis is placed on multicomponent reactions, C–H functionalization, oxidative cyclization, and nanoparticle-catalyzed processes. Mechanistic insights, green chemistry aspects, advantages, and limitations are critically analyzed. The study highlights the transformative role of ionic liquids in improving efficiency, selectivity, and sustainability of organosulfur synthesis, while identifying future research directions for industrial scalability and environmentally benign processes.

Keywords: Ionic liquids, Sulfur-based heterocycles, Green synthesis, Multicomponent reactions, Nanoparticle catalysis, Sustainable chemistry.
