Graphical Abstract

Electroreductive cross-electrophile coupling (eXEC) has emerged as a practical, green, sustainable, efficient electrochemical and controllable approach for constructing C−C or C−X bonds through selective cross-coupling of different electrophiles. This Mini-review summarizes the recent protocols of electroreductive cross-electrophile coupling reactions.

Abstract

Electrochemistry utilizes electrons as a potent, controllable, and traceless alternative to chemical oxidants or reductants, and typically offers a more sustainable option for achieving selective organic synthesis. Recently, the merger of electrochemistry with readily available electrophiles has been recognized as a viable and increasingly popular methodology for efficiently constructing challenging C−C and C-heteroatom bonds in a sustainable manner for complex organic molecules. In this mini-review, we have systematically summarized the most recent advances in electroreductive cross-electrophile coupling (eXEC) reactions during the last decade. Our focus has been on readily available electrophiles, including aryl and alkyl organic (pseudo)halides, as well as small molecules such as CO2, SO2, and D2O.
