A facile, efficient and general protocol for synthesizing a series of mono-, bisand tris-arylsubstituted anilinederivatives is described via the Pd(OAc)2-catalyzed aerobic and ligand-free Suzuki reaction of mono-, diand tribromoanilines with aryl boronic acids in aqueous N,Ndimethylformamide (DMF). This is the first example to prepare 2,6-bisaryl-4-nitroanilines and 2,6-bisarylanilines via a palladium-catalyzed
