Deep eutectic solvents: cutting-edge applications in cross-coupling reactions

Abstract

Deep eutectic solvents and their physicochemical properties as task-specific and designer solvents for cross-coupling reactions, are appraised.

Use of ammonium salts or binary mixtures derived from amino acids, glycine betaine, choline and indole-3-butyric acid as plant regulators

“…Energy consumption and production costs must be considered in the design of novel 'green' compounds. 1 Ammonium salts (including ionic liquids, ILs) [2][3][4][5][6] or binary mixtures (including eutectic mixtures) [7][8][9][10] are perfectly compatible with this trend. However, not every IL or binary mixture conforms to green chemistry guidelines.…”

Eco-Friendly 1,3-Dipolar Cycloaddition Reactions on Graphene Quantum Dots in Natural Deep Eutectic Solvent

“…The recycling of green solvents is in fact an important issue in order to increase the sustainability of a chemical process. As reported in other studies, the water solubility of NADES can be exploited for their easy recovery by simple water extraction and also for their reuse [ 37 , 41 ].…”

Ligand‐Free Suzuki–Miyaura Cross‐Coupling Reactions in Deep Eutectic Solvents: Synthesis of Benzodithiophene Derivatives and Study of their Optical and Electrochemical Performance

“…Because of a low ecological footprint and unusual physicochemical properties, DESs are progressively replacing toxic, petroleum-derived VOCs in several fields of science. New emerging applications are related to organometallics, [25][26][27] metal-, [28][29][30][31][32][33][34] bio-, [35][36][37][38][39] and organocatalysis, [40][41][42] electrochemistry, [43] photosynthesis, [44] and solar technology. [45][46][47] Building upon our recent findings on metal-catalyzed crosscoupling reactions run in DESs in the absence of additional ligands, [30][31][32] herein we report a systematic study aimed at performing Suzuki-Miyaura (SM) coupling reactions between dibromo or diiodo BDT derivatives and (hetero)aryl-, alkenyl-and alkynyl boronic species in DESs, under ligandless and mild conditions.…”
