A metal-free visible-light-promoted regioselective C-3 sulfenylation of imidazo[1,2-a]pyridines and indoles using thiols has been developed via C(sp²)–H functionalization. This method provides direct access to a wide range of structurally diverse 3-sulfenylimidazopyridines of biological interest. The operational simplicity, eco-energy source, high atom efficiency, and the use of green solvents under ambient conditions are some of the attractive features of this methodology.

在无过渡金属的条件下可见光诱导的巯基咪唑并吡啶的区域选择性亚磺酰化

通过C（sp ²）–H官能团开发了一种无金属的可见光促进的咪唑并[1,2- a ]吡啶和吲哚类吲哚类化合物的C-3区域选择性C-3亚磺酰基。该方法提供了直接接触生物感兴趣的结构上广泛的3-亚磺酰基咪唑并吡啶的途径。操作简便，生态能源，高原子效率以及在环境条件下使用绿色溶剂是该方法的一些吸引人的特征。
