Dinitrobenzene and 3-nitropyridine react with lithium arylamides underanaerobicconditions to produce N-aryl-2,4-dinitroanilines and N-aryl-5-nitropyridin-2-amines, respectively, in 8-42% yields.
Herein, C–N cross coupling methodology was developed for the synthesis of a diverse range of nitro-substituted secondary amines. A variety of strained, aliphatic, and aromatic precursors were effectively used, with low catalyst and ligand loading ratios resulting in product formation in good yield. This method can act as an alternative to nucleophilic addition reactions. To cross couple electron-donating
