An efficient electrochemical method for benzylic C(sp3)–H bond oxidation has been developed. A variety of methylarenes, methylheteroarenes, and benzylic (hetero)methylenes could be converted into the desired aryl aldehydes and aryl ketones in moderate to excellent yields in an undivided cell, using O2 as the oxygen source and lutidinium perchlorate as an electrolyte. On the basis of cyclic voltammetry
已经开发了一种用于苄基 C(sp 3 )-H 键氧化的有效电化学方法。各种甲基芳烃、甲基杂芳烃和苄基(杂)亚甲基可以在未分割的电池中以中等至极好的收率转化为所需的芳醛和芳酮,使用 O 2作为氧源,高氯酸镥作为电解质。在循环伏安法研究、18 O 标记实验和自由基捕获实验的基础上,提出了一种可能的单电子转移机制用于电氧化反应。
