Abstract
Abstract The use of CO 2 as a C1 building block to access carboxylic acids is one of the key aspects in the context of carbon capture and utilization (CCU). Herein we report on an electrochemical carboxylation of allyl esters with CO 2 at atmospheric pressure. This strategy enabled to the synthesis of diverse carboxylic acids without the need for a transition metal catalyst. Furthermore, the mechanism was studied through ICP‐MS analysis and cyclic voltammetry studies for the cross‐electrophile CO 2 coupling.
