Electrochemical oxidation of some catechol derivatives has been studied in the presence of 1,3-indandione as nucleophile in aqueous solution, by means of cyclic voltammetry and controlled-potential coulometry. The results indicate the participation of electrochemically produced o-benzoquinones in the Michael reaction with 1,3-indandione to form the corresponding new catechol derivatives. On the basis
一些儿茶酚衍生物的电化学氧化已通过循环伏安法和受控电位库仑法在 1,3-茚满二酮作为亲核试剂的水溶液中进行了研究。结果表明,电化学产生的邻苯醌参与了与 1,3-茚二酮的迈克尔反应,形成了相应的新儿茶酚衍生物。在 EC 机制的基础上,通过将实验循环伏安图与数字模拟结果进行比较,估计了生成的邻苯醌与 3-茚满二酮反应的均相速率常数 (kobs)。© 2007 Wiley Periodicals, Inc. Int J Chem Kinet 39: 605–613, 2007
