Paragraph 0029; 0033-0037, (2020/10/04)
The invention relates to a synthetic method of a diarylsulfone compound. The method is characterized in that a copper complex and aryl sulfonyl hydrazide are dissolved in an organic solvent, air serves as an oxidizing agent, a reaction is conducted at the room temperature, separation and purification are conducted to obtain the corresponding diarylsulfone compound, the molar ratio of the copper complex to the aryl sulfonyl hydrazide is (0.01-0.03):1.0, and the reaction time is 2-5 h. Compared with the prior art, the synthesis process provided by the invention has excellent selectivity and highyield, the catalyst copper complex in the reaction can catalyze the self-coupling of aryl sulfonyl hydrazide to synthesize the diarylsulfone compound at room temperature, and the reaction has the characteristics of mild and simple conditions, wide substrate range, convenient product separation, high reaction efficiency and the like.
