A practical photoredox and cobalt co-catalyzed C(sp²)–H functionalization/C–O bond formation is described herein, with dihydrogen as the only by-product. A variety of lactone products can be successfully constructed under oxidant- and acceptor-free conditions with good functional group tolerance and high yield. This protocol also provides a facile route to remote hydroxylated arenes and chromene.

光氧化还原和钴共催化C（sp ²）–H官能化/ C–O键形成，可在无氧化剂和无受体条件下合成内酯

本文描述了一种实用的光氧化还原和钴共催化的C（sp ²）-H功能化/ C-O键形成，其中二氢是唯一的副产物。各种内酯产品可以在无氧化剂和无受体的条件下成功构建，具有良好的官能团耐受性和高收率。该协议还提供了通往远程羟基化芳烃和亚甲基苯的简便途径。
