Specifically, we show that the first electrochemical reduction of acetophenone is followed by the homogeneous chemical addition of CO2. The electrochemical reduction of the acetophenone-CO2 adduct is more facile than that of acetophenone, resulting in an Electrochemical-Chemical-Electrochemical (ECE) reaction pathway that appears as a single voltammetric wave. These modeling results pro- vide new fundamental insights on the complex microenvironment in CO2-rich media that pro- duces an optimum electrochemical carboxylation rate as a function of CO2 pressure.Read More
