Ionic Liquid Immobilized Organocatalysts for Asymmetric Reactions in Aqueous Media

“…As a result, the IL immobilized catalyst is regenerated and can be used for further reactions. Water is known to be the cheapest, environmentally benign, safe and most abundant compound on the earth's surface; and it has attracted a great deal of attention from a green chemistry perspective [33][34][35][36][37][38][39][40][41][42][43]. In addition, water also holds some unique physical and chemical properties, such as high surface tension, hydrogen bonding capability, high dielectric constant and high cohesive energy density [44][45][46].…”

Recycling and Elimination of Wastes obtained from Agriculture by using Nanotechnology: Nanosensors

“…The afore mentioned paper report a simple, cost-effective procedure to produce gold nanoparticles that are stable with extended shelf life. Recent reports have shown an increased use of water as solvent in chemical reactions instead of organic solvents [32]. The water dispersible nature of gold nanoparticles from grape byproducts along with its inherent health benefits can revolutionize the impact of nanotechnology on drug/nutraceutical delivery.…”

Green Chemistry – Aspects for the Knoevenagel Reaction

“…Water as a solvent is not only inexpensive and environmentally benign but also provides completely different reactivity (Li & Chen, 2006). It has been suggested that the effect of water on organic reactions may be due to the high internal pressure exerted by a water solution, which results from the high cohesive energy of water (Breslow, 1991).…”
