Synthesis of 2-(2H-1,2,3-triazole-2-yl)aniline derivatives from 2-aryl-1,2,3-triazoles and sulfonylazides through ruthenium-catalyzedintermolecular C–H amidation is achieved. This reaction provides an environmentally benign protocol for C–N bond formation, producing N2 gas as the sole byproduct. Yet a number of functionalities are well tolerated, obtaining the desired products in moderate to excellent
通过钌催化的分子间CH键酰胺化反应,可以从2-芳基-1,2,3-三唑和磺酰叠氮化物合成2-(2 H -1,2,3-三唑-2-基)苯胺衍生物。该反应为C–N键的形成提供了一种环境友好的方案,可产生N 2气体作为唯一的副产物。然而,许多功能被很好地耐受,以中等至极好的产量获得了所需的产品。
