Palladium-catalyzed intermolecular C–N bond-forming reactions between aryl halides and amides are described using 2-dialkylphosphino-2′-alkoxyl-1,1′-binaphthyl, which is both bulky and electron-rich, as the ligand. A variety of amides, including aliphatic and aromatic primary amides, lactams, and carbamates, were viable substrates for the amidation, which exhibited good functional group compatibility
芳基卤化物和酰胺之间的钯催化的分子间C–N键形成反应是使用2-二烷基膦基-2'-烷氧基-1,1'-联萘作为配体来描述的。各种酰胺,包括脂族和芳族伯酰胺,内酰胺和氨基甲酸酯,都是酰胺化的可行底物,它们具有良好的官能团相容性。通过调节配体1,1'-联萘的2,2'-位上的取代基,实现了钯催化的大体积芳基卤化物的酰胺化反应,该偶联反应用于合成2-氨基-2'-甲氧基-1,1'-联萘的收率很高。
