The electrochemical oxidation of catechols was described and has shown that these compounds can be oxidized to related o-benzoquinones. The electrochemically generated o-benzoquinones are quite reactive and can be attacked by a variety of nucleophiles under various mechanistic disciplines such as CE, EC, EC′, ECE, ECEC, ECEC ₂, ECECE, ECECEC, ECECECE and trimerization, in which E represents an electron transfer at the electrode surface, and C represents a homogeneous chemical reaction. The mechanistic pathways and final products are depending on some parameters such as electron withdrawing or donating properties of nucleophile, electrolysis medium (solvent, acidity or pH) and nature of catechol.

均相反应与邻苯二酚的电化学氧化机理研究

描述了儿茶酚的电化学氧化，并显示这些化合物可被氧化为相关的邻苯并醌。电化学生成的邻苯醌具有很强的反应性，并且在各种机理下，例如CE，EC，EC'，ECE，ECEC，ECEC ₂，ECECE，ECECEC，ECECECE和三聚化作用下，可以被多种亲核试剂攻击电子在电极表面转移，C表示均匀的化学反应。机械途径和最终产物取决于某些参数，例如亲核试剂的吸电子或给电子性质，电解介质（溶剂，酸度或pH）和邻苯二酚的性质。
