Abstract
Electrochemical oxidation of catechol has been studied in the presence of imidazole as
nucleophile in aqueous solution, using cyclic voltammetry. The results indicate the
participation of catechol in 1, 4- Michael reaction with imidazole to form the corresponding
catechol thioethers. Based on the observed EC mechanism, the homogeneous rate constants
(kfcal) of the reaction of o-benzoquinone with imidazole were estimated by fitting the
theoretical working curve with the experimental working curve.
Key words: EC mechanism, cyclic voltammetry, catechol and imidazole.
