Abstract :
Electrochemical oxidation of 4-tert-butylcatechols (1) has been studied in the
presence of N,Nʹ-dimethylamino ethanthiol (3) as nucleophile in aqueous solution, using
cyclic voltammetry and controlled-potential coulometry. The results indicate the
quinone derived from the oxidation of 4-tert-butylcatechols (1) participates in a Michael
addition reaction with N,Nʹ-dimethylamino ethanthiol (3) to form the corresponding
arylsulfonylbenzenediol 4 as the final product. Based on an EC mechanism, the
observed homogeneous rate constants of reaction of some catechol derivatives and 3
were estimated by comparison the experimental cyclic voltammograms with the digital
simulated results.
