| Abstract: | P,N-ligands(L1-L5) with cyclic secondary amine moieties linked to the benzene rings of triphenylphosphine were designed and synthesized for the palladium-catalyzed C-N bond coupling reactions.The structures of these new P,N-ligands were confirmed by 1H NMR,13C NMR,31P NMR,infrared,high resolution mass spectroscopy,and X-ray single crystal diffraction.The desired C-N bond coupling products were obtained in good to excellent yields(up to 95%) when the reactions of aryl bromides with secondary amines were perf... |
