In this report, the highly efficient Rose Bengal-catalysed C(sp)-H selenylation of indoles, imidazoles and arenes was achieved using a half molar equiv. of diorganoyl diselenides. This metal-free, photo-induced protocol resulted in selenylated products in good to excellent yields. The reaction features are high yields, an atom-economic, gram-scalable and metal-free approach, and applicability to different biologically relevant (hetero)arenes.
在本报告中，使用半摩尔当量的二芳基二硒醚，实现了高效的 Rose Bengal 催化吲哚、咪唑和芳烃的 C(sp)-H 硒化反应。该无金属、光诱导的反应方案得到了良好至优秀收率的硒化产物。该反应具有高产率、原子经济性、克级规模和无金属、以及对不同生物相关（杂）芳烃适用性的特点。
