Juni 135,D-10623 Berlin (Germany)The utility of cheap, clean and renewable energy source such as the solar energyto induce the chemical reactions serves as a promising way for the cost-effective andgreen chemical synthesis [1]. Recent years have witnessed the growing interest inphotochemical transformations as the activation of substrate may happen withoutadditional reagents under the principle of green chemistry.Recently, we introduced a simple and potentially abundant polymericsemiconductor, a weakly disordered version of graphitic carbon nitride (g-C 3 N 4 ) as ametal-free photocatalyst for hydrogen evolution with visible light [2]. The light-inducedelectron with large reduction potential can easily activate molecular oxygen tomediate energy and electron transfer while the moderate oxidation potential of theholes prevents the synthesized organics from deep oxidation in an uncontrollablemanner. This feature suggested that g-C 3 N 4 can act as a gentle photocatalyst forpromoting organic redox synthesis in a broader fashion.Scheme 1. mpg-C 3 N 4 -catalyzed Aerobic Oxidative Coupling of Amines.567
