The electrochemical oxidation of 1,4-dihydroxyanthraquinone has been studied in the presence of acetylacetone and benzoylacetone as nucleophiles in a mixture of ethanol/water by means of cyclic voltammetry as a diagnostic technique. The results indicate the participation of electrochemically produced anthraquinone in the Michael addition reaction with acetylacetone and benzoylacetone to form the corresponding
已经通过循环伏安法作为诊断技术,研究了在乙醇/水混合物中以乙酰丙酮和苯甲酰丙酮为亲核试剂存在下的1,4-二羟基蒽醌的电化学氧化。结果表明,电化学产生的蒽醌参与了与乙酰丙酮和苯甲酰基丙酮的迈克尔加成反应,形成了相应的新的蒽醌衍生物。根据EC机理,通过比较实验循环伏安图和数字模拟结果,估算了蒽醌与乙酰丙酮和苯甲酰丙酮反应的观察到的均相速率常数(k obs)。
