Towards sustainable chemistry: Advances, challenges and opportunities in organic electrosynthesis

Organic electrosynthesis is particularly appealing for transformations that would otherwise be challenging because of its intrinsic ability to synthesize extremely reactive species under mild conditions via anodic oxidation or cathodic reduction. It has sparked much attention as an effective, environmentally friendly synthesis tool because it generates less waste, uses fewer chemicals, and often requires fewer reaction steps than previous procedures. The processes that underpin organic electrosynthesis include functional group interconversion and formation of C−C and C−heteroatom bonds (such as C−N, C−O, C−S, and C−H) through a controlled electrode potential. Some of the strategies mentioned as aiding the overall process optimization include the use of indirect electrosynthesis, paired electrochemical processes, and electrochemical microreactors. Furthermore, the use of electrochemical flow reactors has resulted in accurate reaction control and optimization. This review discusses strategic developments in organic electrosynthesis, focusing on fundamental concepts, novel approaches, and future directions for sustainable chemical manufacturing.
