Recent advances and new trends in the use of deep eutectic solvents in organic synthesis and other applications

In this report, the classified applications of deep eutectic solvents (DESs) in different disciplines have been reviewed. DESs have been the most important reaction media for organic reactions during last decades because of their availability, low cost, promising solubility of organic and inorganic compounds, playing dual roles of solvent and catalyst, high temperature tolerance and simple procedure for performing reaction, work-up, and separations steps. Based on the previous reports, they have been vastly employed in separation, extraction, pharmaceuticals, biofuels, biological science and polymer technology. A detailed review of the current literature reveals the lack of a comprehensive review to show the most reported aspects of this class of compounds, focusing on the recent advances and new trends in this area. This report is useful to show the road map for the scientists who do research in each category of this area. To enhance the understanding the potencies of DESs, in each field, a brief list of applications was showed in the table, as well as discussing about the most important topics. The present work identifies potential areas for future studies in this field and the most interested topics related to the use of DESs. Moreover, it covers recent developments in the use of DESs in various field to distinguish the empty spaces, which could be worked out in the future studies.
