Electrochemical Carboarylation of Activated Alkenes with CO2 and Electron-deficient Aryl Bromides

Abstract

The simultaneous construction of two vicinal C—C bonds in a molecule remains a significant challenge. In this work, we disclose an electroreductive carboarylation of activated alkenes under mild, transition metal-free conditions. Utilizing readily available starting materials (electron-deficient aryl bromides, activated alkenes, and CO₂), this method demonstrates broad substrate scope and good functional group tolerance. Notably, this strategy enables the addition of two distinct electrophiles across an alkene in a highly chemo- and regioselective manner.
