New synthesis method of diaryl sulfone compounds

The invention provides a new synthesis method of diaryl sulfone compounds. The method comprises the step of adding alkali into 1,3-propenyl disulfone and beta,gamma-unsaturated ketone ester, which areused as raw materials, at a certain temperature for carrying out a reaction in a solvent so as to obtain the diaryl sulfone compounds with high yield. The method is simple to operate and high in reaction yield, does not need to use a transition metal catalyst, and has a very high application value for the industrial preparation of the diaryl sulfone compounds. 本发明提供了种合成二芳基砜类化合物的新方法。该方法采用1，3-丙烯基二砜及β，γ-不饱和酮酯为原料，在定温度下，加入种碱，在溶剂中反应，即可以优秀的收率得到二芳基砜类化合物。该方法操作简便、反应收率高、反应中无需使用过渡金属催化剂，对于二芳基砜类化合物的工业制备具有很高的应用价值。
