Synthetic methodologies and applications of chalcogen (S, Se, Te) ionic liquids: a review

AbstractIonic liquids (ILs) have emerged as an environmentally friendly alternative to the volatile organic solvents. Though primarily used as solvents, ILs synthesized with specific desired chemical properties have gained significant attention in recent years due to their unique properties and versatile applications in various areas of chemical synthesis and beyond. The present review is aimed at exploring the synthetic methods for chalcogen (S, Se, Te) ionic liquids along with the study of their role as solvent, catalyst, reactant in various chemical reactions like oxidation reactions, hydrothiolation transformations etc., thus showing the contribution of ILs toward the development of sustainable organo-chalcogen chemistry.Keywords: Selenium ionic liquidsrecyclablealternative solventscatalystvolatile organic solvents Disclosure statementNo potential conflict of interest was reported by the author(s).
