Method for synthesizing unsaturated ketone or aromatic ketone compound

Abstract

Disclosed in the present invention is a method for synthesizing an unsaturated ketone or aromatic ketone compound. The method comprises: at a certain temperature, by using an unsaturated hydrocarbon or aromatic hydrocarbon as a starting material and a N-hydroxyimide compound as a catalyst, adding an organic solvent to dissolve same, then introducing oxygen or air into the reaction solution under light irradiation to carry out an oxidation reaction, and performing workup and separation to obtain the unsaturated ketone or aromatic ketone. The method of the present invention uses air, oxygen-enriched gas or oxygen as a harmless oxidant and light as an energy source to promote the reaction, and therefore has the advantages that the reaction process is green and efficient and low-cost, the usage amount of the catalyst is small, and most of the catalyst is recyclable. In addition, the method of the present invention does not require the participation of reagents such as heavy metals, photocatalysts and hypervalent iodine oxidants and thus has high atomic economy.
