Solvent dependent reaction mechanisms in the electrooxidative coupling of phenols: Insights by operando Raman spectroelectrochemistry

Abstract

The electrochemical oxidative phenol coupling reaction is a sustainable method for accessing biphenolic compounds. Using the dimerization of sesamol as model reaction, insights into the reaction mechanism were gained via operando Raman spectroscopy. By varying solvent and electrodes, different reaction mechanisms were identified and correlated with the respective product yields.
