In the present work, a series of steric substituted α-imino-amido palladium complexes, {[Ar-NC(CH3)-C(CH3)(R)-NH-Ar] PdCl2} (C1, R = Me, Ar = 2,6-dimethylphenyl; C2, R = Me, Ar = 2,6-diisopropylphenyl; C3, R = CH2Ph, Ar = 2,6-dimethylphenyl; C4, R = CH2Ph, Ar = 2,6-diisopropylphenyl), were synthesized and characterized. The structures of palladium complexes C3 and C4 were elucidated by X-ray diffraction. These bidentate nitrogen ligands were applied in palladium-catalyzed Suzuki-Miyaura cross-coupling reactions. The effect of ligand substitution as well as reaction conditions on catalytic activity was evaluated. Under the optimization process, the less bulky and electron-donating ligand were successfully used to catalyze the reaction of a variety of aryl bromides and chlorides with arylboronic acids, giving the desired biaryl products in high yields.
