| titleOfInvention | A kind of synthetic method of N,N`-diarylbenzohydrazide compound |
| abstract | The invention relates to a method for synthesizing N,N'-diaryl benzoic hydrazide compounds. The method comprises adding azobenzene compounds and α-keto acids into dichloromethane, and irradiating them with visible light at room temperature. Stir until the reaction is complete to obtain a reaction mixture; after the reaction mixture is distilled under reduced pressure to remove the solvent and silica gel column chromatography, N,N'-diarylbenzohydrazide compounds are obtained. The present invention is the first time to synthesize a large number of N,N'-diarylbenzoic hydrazides through the hydroacylation reaction of azobenzene compounds and α-keto acids promoted by visible light, which not only avoids the use of any catalyst, ligand and Additives, and the reaction temperature is room temperature, the yield is high, the atom economy is good, and the by-product is only carbon dioxide, which meets the requirements of green chemistry and sustainable development. |
