A highly efficient and environmentally friendly method for catalytic chalcogenylation of imidazopyridines, imidazopyrimidines, indoles, and pyrrolo[2,3-b]pyridines with dichalcogenides has been developed by using CuI as catalyst under air. The reactions proceed smoothly to give the desired products in moderate to excellent yields, without the presence of other additive.
通过在空气中使用CuI作为催化剂,开发了一种高效的,环境友好的方法,该方法用于用二硫代甲烷催化咪唑并吡啶,咪唑并嘧啶,吲哚和吡咯并[2,3- b ]吡啶。反应平稳进行,以中等至优异的产率得到所需产物,而没有其他添加剂的存在。
