A mild, practical method to prepare α-sulfonyl and α-trifluoromethyl ketones from readily available enol acetates and sulfonyl chlorides has been developed using visible-light photoredox catalysis. The method could be used with a wide range of enol acetates and sulfonyl chlorides, and gave the desired products in satisfactory to excellent yields. A practical method to prepare α-sulfonyl and α-trifluoromethyl ketones from enol acetates and sulfonyl chlorides using visible-light photoredox catalysis is presented. Copyright

Paragraph 0039-0042; 0139-0142, (2020/12/09)
The invention discloses a preparation method of a beta-carbonyl sulfone compound, and belongs to the technical field of organic synthesis. The preparation method of the beta-carbonyl sulfone compoundis provided for solving the problems that in the prior art, operation is complex, the substrate range is narrow, and the functional group tolerance is poor. The preparation method comprises the stepsof taking a compound shown in formula I and a compound shown in formula II as raw materials, taking copper salt as a catalyst, carrying out reaction in an organic solvent, and after the reaction is completed, carrying out aftertreatment to obtain the beta-carbonyl sulfone compound. The preparation method is simple and convenient to operate, mild in reaction condition, wide in substrate range and good in functional group tolerance, the yield reaches up to 93%, and the synthesis cost is remarkably reduced.
