Ionic liquid-assisted synthesis of pyrrole derivative: a green and sustainable method

Green synthesis is attracting researchers worldwide because of its unique features and environmental benefits. Scientists are inventing novel ionic liquids (ILs) and refining their properties for use in green chemistry and synthesis, such as in green and sustainable solvents and catalysts. Owing to their unique properties, they have been widely used as green catalysts and solvent systems to develop various significant heterocycles. Among aza-heterocycles, pyrrole derivatives are regarded for their versatility in medication development and research. Organic chemists have developed pyrrole-based frameworks employing ILs as solvents and catalysts, achieving major green and sustainable synthesis goals. This study focuses on the literature (2001–24) on pyrrole and its derivatives synthesised by using ILs as solvents and catalysts.
