Electrochemical oxidation of catechols (1a—c) has been studied in the presence of 2-hydroxy-1,4-naphtoquinone (3b) in aqueous solutions, using cyclic voltammetry and controlled-potential coulometry. The results indicated that the electrochemically generated o-benzoquinones (2a—c) participate in Michael addition reaction with 3b to the corresponding benzofuranoquinones (8a—c, 10a—c). The electrochemical synthesis of these compounds has been successfully preformed at a carbon rod electrode with good yields using an environmentally friendly method.
在水溶液中,使用循环伏安法和控制电位库仑法,研究了儿茶酚(1a—c)在2-羟基-1,4-萘醌(3b)存在下的电化学氧化。结果表明,电化学生成的邻苯醌(2a—c)参与了与3b的迈克尔加成反应,形成了相应的苯并呋喃醌(8a—c,10a—c)。通过环境友好的方法,在碳棒电极上成功合成了这些化合物,且产率良好。
