A copper-catalyzed novel synthesis of symmetric diarylamines was achieved from aryl boronic acids and NaNO2. This protocol employs as the commercially available arylation reagents sodium nitrite (NaNO2) cheap, stable, solid amino source. Under a simple ligand- base-free copper catalytic system (CuCl sole catalyst), wide range could be obtained in moderate to good yields. Notably, use Na15NO2 produce 15N-labeled diarylamines, which would otherwise difficult prepare by known methods.

CuI/6-hydroxy picolinohydrazide-catalyzed coupling of (hetero)aryl chlorides with anilines proceeded well at 100 °C to afford biaryl amines in a diverse manner, which represents the first example Cu-catalyzed under milder conditions. The same catalytic system could make bromides work room temperature, giving corresponding products an excellent reaction scope.
