The need for a more sustainable synthesis of organic compounds is undeniable. The replacement of volatile organic compounds (VOCs) as solvent media in organic transformations is crucial to access valuable organic products in an environmentally benign manner.
Among the neoteric solvents available for this purpose, Deep Eutectic Solvents (DES) have gained increased attention in recent years. Although eutectic mixtures have been known for centuries, it was not until 2003, when Andrew Abbott coined the term DES, that the use of these solvents started to be explored in several research fields. DESs, defined as mixtures of pure compounds for which the eutectic point temperature is below that of an ideal liquid mixture, meet the requirements to be considered as green solvents. Apart from the fact that they have a negligible boiling point, easy preparation, low cost, low toxicity, or high biodegradability, DESs also provide the possibility of tailoring their physicochemical properties to the chemical process, making this a relevant feature for organic synthesis. In addition, most DESs are obtained through a simple extraction with water, allowing the easy separation of the organic products from the DES. However, if catalysts are needed for the transformation, the catalyst/DES system can be designed to recover the catalysts after the reaction has taken place. Furthermore, some unique properties such as gas solubility and the stability of radical intermediates have provided the opportunity to discover novel reactivities.
In this Special Issue, we intend to compile the latest achievements in the use of DESs in organic transformations as the solvent media. Especially in catalyzed reactions, whether a DES is used as a solvent or as the catalyst, the focus will be on its possible recycling and reuse. The goal of this Special Issue will be to advance the state-of-the-art in this field and further explore the new prospects offered by DESs in organic synthesis.
