Study on Suzuki Cross-Coupling Reactions of Novel Electrophilic Substrate with Phenyl Boronic Acid Catalyzed by Palladium

The Suzuki cross-coupling of aryltriazene with phenylboronic acid catalyzed by transition metal catalyst was achieved.The reaction was performed at room temperature under an argon atmosphere.Catalysts,effect of solvent,aryltriazene/phenylboronic acid ratio and the catalyst loading on the cross-coupling reaction were investigated.The scope of this coupling reaction was explored under optimized reaction conditions.Most of the cross-coupling reactions afforded biaryl products in good to excellent yields.The results indicate that this method has good substrate generality.
