A non-noble metal-free protocol has been developed for C–H bond functionalization at room temperature by merging cobalt-mediated catalysis with photocatalysis. The reaction requires only oxygen as sole oxidant and operated at room temperature under redox-neutral conditions. Visible-light activated photoredox catalyst functions as an electron transfer reagent with oxygen as a terminal oxidant in the cobalt-mediated C–H and N–H bond annulation. The developed methodology allows annulations with various coupling partners. The concept demonstrated herein is expected to enhance the scope of cobalt catalysis as applied to sustainable fine chemical synthesis.

通过合并钴和光氧化还原催化作用的室温C–H键官能化
通过将钴介导的催化作用与光催化作用结合起来,已开发出一种非贵金属的协议,用于在室温下进行C–H键功能化。该反应仅需要氧气作为唯一氧化剂,并在氧化还原中性条件下于室温下进行。可见光活化的光氧化还原催化剂在钴介导的C–H和N–H键环化中以电子作为转移剂,氧为末端氧化剂。所开发的方法允许与各种耦合伙伴进行环空。预期本文所证明的概念将扩大钴催化应用于可持续精细化学合成的范围。
