An efficient and mild method using a bimetallic MnF2/CuI catalyst at 60 °C in water was developed for the N-arylation of amides and sulfonamides with aryl halides. A variety of functionalized amides and sulfonamides were coupled with different substituted aryl halides to afford the corresponding N-arylated products in good to excellent yields (up to 97 %).
开发了一种在 60 °C 下在水中使用双金属 MnF2/CuI 催化剂的有效且温和的方法,用于酰胺和磺酰胺与芳基卤化物的 N-芳基化。各种官能化酰胺和磺酰胺与不同的取代芳基卤化物偶联,以良好至极好的产率(高达 97%)提供相应的 N-芳基化产物。
