A copper/silver-cocatalyzed protocol for oxidative sulfonylation of hydrazones is demonstrated. A wide range of β-ketosulfones and N-acylsulfonamides are directly synthesized in moderate to good yields. Our work provides a viable method for scalable preparation of β-ketosulfone derivatives that have found wide applications in the pharmaceutical industry.

The invention discloses a method for synthesizing a high-added-value alpha-sulfone ketone compound from an alpha, alpha-dibromo ketone compound by a one-pot process. The method has the advantages thatan alpha-sulfone ketone derivative is synthesized from alpha, alpha-dibromo ketone, which is simple and easy to obtain, by the one-pot process without separation of an alpha-bromo ketone intermediate, so that a separation process for an intermediate product is omitted, the steps are reduced, and requirements for environment protection are met; the steps of the method are simple and easy to operate, no transition metal reagents are required, and economical sulfonate with less pollution is directly used as a promoter and a sulfonating agent for reducing debromination of the alpha, alpha-dibromoketone, so that the cost is reduced, and economic benefits of reactions are increased; a system for preparing the alpha-sulfone ketone derivative by the one-pot process is developed to provide a novel synthesis method for preparation of the alpha-sulfone ketone compound, and the method has good industrialization prospect and potential application value.
