  • Electrochemical oxidation of catechols in the presence of 4-hydroxy-6-methyl-2-pyrone
    作者:Davood Nematollahi、Zinat Forooghi

    Electrochemical oxidation of catechols (1a–1c) has been studied in the presence of 4-hydroxy-6-methyl-2-pyrone (3) as nucleophile in aqueous solution, using cyclic voltammetry and controlled-potential coulometry. The results indicate that the quinones derived from catechols (1a–1c) participate in Michael addition reactions with 3 to form the corresponding heterocyclic compounds (6a–6c). In this work
    使用循环伏安法和可控电库仑法研究了在水溶液中以亲核试剂形式存在的4-羟基-6-甲基-2-吡喃酮(3)对儿茶酚(1a – 1c)的电化学氧化。结果表明,衍生自邻苯二酚的醌(1a - 1c)与3参与迈克尔加成反应,形成相应的杂环化合物(6a - 6c)。在这项工作中,我们提出了一种电极处理的机制。6a – 6c的电化学合成已成功地在碳棒电极和未分割的电池中进行。
