Beyond CO 2 reduction: Electrochemical C-N coupling reaction for

The electrosynthesis of organonitrogen compounds via coreduction of carbon dioxide (CO2) and nitrogenous molecules is regarded as a promising green technology for sustainable and reliable chemical production. Although many researchers have reported on electrochemical C-N coupling reactions, these reactions are still insufficient for use in the commercial industry. In this work, we provide a comprehensive review of the fundamental reaction mechanism of electrochemical C-N coupling and strategies for improving the electrosynthesis of organonitrogen compounds. Additionally, we discuss the current challenges, extended electrochemical coupling reactions, and future roadmaps of electrochemical C-N coupling reactions. This review will strongly enhance the understanding of electrochemical C-N coupling reactions and propose a way forward for the electrosynthesis of organonitrogen compounds.
