Here we disclose a general Co(II/III/IV) electrocatalytic platform for alkene functionalization. Driven by electricity, a set of the oxidative hydrofunctionalization reactions via hydrogen atom transfer were demonstrated without the need for stochiometric chemical oxidants. The scope of the reactions encompasses hydroalkoxylation, hydroacyloxylation, hydroarylation, semipinacol rearrangement, and deallylation
在这里,我们公开了一种用于烯烃官能化的通用 Co(II/III/IV) 电催化平台。在电力驱动下,证明了一组通过氢原子转移的氧化氢官能化反应,不需要化学计量的化学氧化剂。反应范围包括加氢烷氧基化、加氢酰氧基化、加氢芳基化、半频哪醇重排和去烯丙基化。机理研究和立体化学证据支持涉及电化学生成的有机钴 (IV) 中间体的 ECEC 过程。这项工作通过超越 Co(I/II/III) 的常见氧化态,展示了 VB 12系统中电催化中反应性空间扩展的示例。
