Electrochemical oxidation of resorcinol: mechanistic insights from experimental and computational studies.

ABSTRACT: This work investigates the mechanisms of resorcinol oxidation by density functional theory (DFT) calculation and cyclic voltammetry measurements. Complementary data from experimental and computational studies provide new insights into the reaction mechanisms. At both macro- and micro-electrodes, cyclic voltammetry of resorcinol is chemically and electrochemically irreversible over the whole pH range (1-14). Resorcinol molecules undergo a 1H⁺ 1e^- oxidation at pH < pK _a1 and a 1e^- oxidation at pH > pK _a2 to form radicals. The radicals then readily react to form dimers/polymers deposited on the electrode surface. All of the experimental findings are consistent with the proposed mechanisms, including the apparent transfer coe
