Employing a two‐dimensional covalent organic framework as the reusable solar photosensitizer, the sunlight‐driven aerobic oxidative construction of a nitrogen‐sulfur bond has been achieved. 3,5‐Disubstituted 1,2,4‐thiadiazoles are smoothly prepared in water by using this procedure. Furthermore, a radical mechanism with a sunlight‐promoted single electron transfer (SET) process is proposed for this transformation.

通过可重复使用的共价有机骨架催化氮硫键的氧化结构，在阳光驱动下合成1,2,4-噻二唑

利用二维共价有机框架作为可重复使用的太阳能光敏剂，实现了由阳光驱动的氮硫键的好氧氧化结构。使用此程序可在水中平稳制备3,5-二取代的1,2,4-噻二唑。此外，针对这种转变，提出了具有阳光促进的单电子转移（SET）过程的自由基机理。
