Palladium-catalyzed Suzuki–Miyaurareaction is an important synthetic strategy for the synthesis of biaryl compounds. This work describes that palladiumcomplexes with N,O-bidentate ligands bearing N-oxide units from cyclic secondary amines were used as highly efficient catalysts for Suzuki–Miyaurareactions of aryl halides with arylboronic acids. The reaction exhibited good functional group compatibility
