Electrochemical Deaminative Carboxylation of Aryltriazenes with CO₂ to Aryl Carboxylic Acids

The utilization of CO₂ as an appealing chemical feedstock for diverse synthetically valuable products is constantly evolving, potentially alleviating chemical production that relies on petrochemistry. Herein we report the first example of the electrochemical deaminative carboxylation of aryltriazenes with CO₂. The reaction can be performed under mild and catalyst-free conditions by using sustainable methods with CO₂ as a green C₁ building block, efficiently converting a diverse range of readily available aryltriazenes into synthetically valuable carboxylic acids. In particular, the formation of C-C bonds by deaminative carboxylation would be an impactful addition to the synthesis toolbox.
