Abstract

The electrochemical oxidation of tetramethoxy precursors (2) to coenzymes Q n (1) at a carbon anode was investigated both in a bench-scale batch electrochemical reactor and in a continuous recirculation reaction system equipped with a parallel-plate electrochemical divided cell. High faradic efficiency (>60%) and excellent selectivity (>90%) in coenzymes Q n were obtained in CH3CN or CH3CN/CH2Cl2 + 0.15 M Bu4NBF4 under potentiostatic or amperostatic alimentation.
