by using 2-amino alkylbenzimidazole (MBIP amine) as a new and removable N,N-bidentate directing group. This strategy gives a variety of functionalized thioethers in moderate to excellent yields in a simple and efficient way. Importantly, the substrate scope is not limited to aromatic amides; diverse alkenyl amides are also compatible. Furthermore, this synthetic approach provides a potentially feasible
通过使用 2-氨基烷基苯并咪唑(MBIP 胺)作为新的可移除 N,N-双齿导向基团,实现了铜促进的 C(sp2)-H 键与二硫化物的硫醇化。该策略以简单有效的方式以中等至极好的收率提供了各种功能化硫醚。重要的是,底物范围不限于芳香酰胺;多种链烯基酰胺也可相容。此外,这种合成方法为通过直接 C-H 活化实现相关含苯并咪唑化合物的结构修饰提供了一种潜在可行的方法。
