Preparation and Characterization of New Compound by Electrochemical Oxidation of Methyl Catechol in the Presence of 2-Thiouracil

The electrochemical oxidation of methyl catechol in the presence of 2-thiouracil (as a nucleophile) has been performed in aqueous solutions using cyclic voltammetry and controlled-potential coulometric techniques. The electrochemical behavior of methyl catechol in the presence of 2-thiouracil was investigated. The electrochemical synthesis of this compound has been successfully performed in an undivided cell in a good yield and purity and was characterized by IR, 1H and 13C NMR. According to the results obtained from 1H NMR, 13C NMR it is concluded that methyl o-quinones are attached in all probably only in the its C4 position to 2-thiouracil from S position leading to the formation of 2-(4,5-dihydroxy-2-methylphenylthio)pyrimidin-4(3H)-one (DMPTP).
