Abstract:A fast, convenient and ligand-free protocol for the synthesis of a series of 4-aryl-substituted triphenylamine derivatives by a palladium-catalysed aerobic Suzuki reaction of aryl halides with [4-(diphenylamino)phenyl] boronic acid in aqueous iPrOH is described. Importantly, both aryl bromides and heteroaryl halides afforded good to excellent yields under mild conditions.
