摘要：The air-stable and easy to prepare nonsymmetric Schiff base ligands have been synthesized and proven to be efficient ligands for Suzuki cross-coupling reaction between aryl bromides and arylboronic acids using PdCl2(CH3CN)2 as palladium source under aerobic conditions. The coupling reaction proceeded smoothly using N-[(3,4-dimethoxyphenyl)methylene]-1,2-benzenediamine (L3) as ligand under mild conditions to provide 4-substituted styrene compounds in good yields.
