pharmacological properties. Herein, we investigate a Cu-catalyzed tandem N-arylation reaction of phthalhydrazides with cyclic iodonium salts to construct dihydrobenzo[c]cinnoline derivatives. Various iodonium salts, such as symmetrical, unsymmetrical, aryl–aryl, and aryl–heteroaryl ones, could react with phthalhydrazides smoothly and give the title products in moderate to high yields. Moreover, the –NH2 group
