Abstract

This short review showcases the developing field of C–H activation reactions, with a particular focus on green catalysis through the use of environmentally friendly solvents. It evaluates the effects of these solvents on reaction outcomes, environmental aspects and general efficacy, highlighting their advantages that lead to greater selectivity, lower levels of toxicity and enhanced reaction rates. Water and biobased alternatives such as polyethylene glycols, glycerol, 2-methyltetrahydrofuran, γ-valerolactone, methanol, ethanol, p-cymene and diethyl carbonate are representative examples of such solvents. The scope of this short review encompasses studies of different methodologies, catalysts, and reaction conditions that help to develop C–H activation reactions utilizing green solvents.
