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.enEC mechanism; cyclic voltammetry; catechol and imidazoleThesis
