Nano Ni/g-C3N4 Photocatalyzed Aerobic Oxidative Coupling Reaction toward Alkyl Aryl Ketones Derivatives under Visible Light Irradiation

In the present study, the synthesis of a group of carbonyl compounds that are widely used in the chemical and pharmaceutical industries was prepared under mild and safe conditions. We developed a new method based on the nickel/carbon nitride (Ni/g-C3N4) dual photocatalytic system to synthesize ketones without using expensive oxidants and heating. This article describes the oxidative coupling reactions between tertiary amines and aryl halides resulting in the production of natural aryl alkyl ketones. It should be noted that all these reactions were carried out using visible light, green solvents under eco-friendly, one-pot conditions, an air atmosphere, at room temperature, without the use of any oxidant.
