Consequent Construction of C–C and C–N Bonds via Palladium-Catalyzed Dual C–H Activation: Synthesis of Benzo[c]cinnoline Derivatives

A highly efficient palladium-catalyzed cascade annulation of pyrazolones and aryl iodides to access various benzo[c]cinnoline derivatives has been achieved at 80 °C. A pyridine-type ligand could im...
