Paragraph 0097; 0107-0113, (2021/06/12)
The invention provides a preparation method of beta-ketosulfoxide based on CaC2 catalysis, and belongs to the technical field of organic synthesis. In the presence of CaC2 or NaH or in the co-presence of CaC2 and TEA, acyl chloride and dimethyl sulfoxide react to prepare the beta-ketosulfoxide compound, the yield of beta-ketosulfoxide is 8.7-78%, and the yield of beta-ketosulfoxide in the reaction process of acyl chloride and dimethyl sulfoxide is remarkably improved. Particularly, in the coexistence of CaC2 and TEA, acyl chloride and dimethyl sulfoxide react to prepare the beta-ketosulfoxide compound, the yield of beta-ketosulfoxide is 45-78%, and the preparation method is green, environmentally friendly, mild in reaction process and simple to operate.
