| Abstract: | Electrochemical oxidation of catechol (1) has been studied in the presence of morpholine (2a), dimethylamine (2b) and diethylamine (2c) as nucleophile in aqueous solution, using cyclic voltammetry and controlled-potential coulometry. The results indicate that the participation of catechol (1) in Michael reaction with 2 to form the corresponding aminoquinone derivatives (5a-5c). Based on ECE mechanism, the homogeneous rate constants were estimated by comparing the experimental cyclic voltammetric responses with the digital simulated results. |
