Sonication in Neoteric Solvents. A Further Look at Synthetic Plans
The use of neoteric solvents to substitute organic molecular solvents offers new opportunities to develop more environmentally friendly synthetic organic chemistry to access to new molecules, materials or processes. Most known and investigated neoteric solvents (NS) remain nowadays supercritical fluids (SCF), room temperature ionic liquids (RTILS) and deep eutectic solvents (DES). Each of them offers several advantages over organic molecular solvents but also display inherent drawbacks. In order to tackle the latter moving forward to safer and faster processes, ultrasound technology was recently coupled synergistically with these new media. These three categories of NS are hereafter briefly introduced together with their own remarkable properties permitting their use as alternative benign solvents. Insights of striking developed applications with ultrasound will be then given in order to unleash the promising potential of coupling ultrasound technology with neoteric solvents.
