A technically feasible method has been developed for the synthesis of variety of aryl malononitriles in high yields (70-95%) using the palladium-catalyzed coupling reaction of malononitrile with aryl bromides and chlorides, respectively. The influence a several reaction parameters such as base, ligand, solvent or temperature were investigated in some detail.
