electrochemical method has been developed for selective benzylic iodination of methylarenes. The reactions feature the first use of N-hydroxyphthalimide as an electrochemical mediator for C-H oxidation to nonoxygenated products. The method provides the basis for direct (in situ) or sequential benzylation of diverse nucleophiles using methylarenes as the alkylating agent. The hydrogen-atom transfer mechanism for
已经开发了一种用于甲基芳烃的选择性苄基碘化的电化学方法。该反应的特点是首次使用 N-羟基邻苯二甲酰亚胺作为 CH 氧化为非氧化产物的电化学介质。该方法为使用甲基芳烃作为烷化剂对不同亲核试剂进行直接(原位)或顺序苄基化提供了基础。CH 碘化的氢原子转移机制允许 CH 氧化在对基板电子特性的依赖性最小的情况下进行,并且电极电位比直接电化学 CH 氧化低 0.5-1.2 V。
