Abstract
Deep eutectic solvents (DESs) are frequently defined as binary or ternary mixtures of compounds that are able to associate mainly via hydrogen bonds. As the interest in green sustainable solvent’s spread over the entire scientific community, DESs find applications as alternative solvents and/or catalysts for organic transformations. Advantages such as easy reproducible preparation, low cost, environmentally benign nature, wide liquid range, excellent thermal stability, negligible vapour pressure, recyclability, and tunable properties render DESs as a sustainable candidate of catalyst/solvent for futuristic transformations involving multicomponent strategy. In view of the escalating demand for green synthetic approaches, this paper retrospects the advances made in the application of DES in multicomponent reactions since 2018.
Keywords: Deep eutectic solvents, multicomponent reactions, green chemistry, catalysis, sustainable chemistry, organic transformations.
