Abstract
Disclosed is a method for preparing β-carbonyl sulfones. The method comprises: by taking an α-carbonyl diazo compound and sodium arylsulfinate as reaction substrates, cheap silver nitrate as an optimal catalyst, 1,10-phenanthroline as a ligand, and potassium persulfate as an oxidant, carrying out coupling reaction in a mixed solvent of acetonitrile and water to obtain a β-carbonyl sulfones compound. Compared with the prior art, the method has the following advantages: a wide range of reaction substrates, short reaction time, a relatively high reaction yield, a mild reaction condition, etc. In the present invention, non-toxic and harmless reagents are used as reaction raw materials, so that it has no harm to the environment and satisfies the requirements of contemporary green chemistry development. Post-reaction treatment is relatively simple, and is convenient for separation and purification. In addition, the reaction can achieve gram-scale synthesis, and lays a foundation for actual applications.
