A Cu-catalyzed cascade oxidative radical process of β-keto sulfones with alcohols has been achieved by using oxygen as an oxidant. In this reaction, β-keto sulfones were converted into sulfinate esters under the oxidative conditions via cleavage of C?S bond. Experimental and computational studies demonstrate that a new pathway is involved in this reaction, which proceeds through the formation of the key four-coordinated CuII intermediate, O?O bond homolysis induced C?S bond cleavage and Cu-catalyzed esterification to form the final products. This reaction provides a new strategy to sulfonate esters and enriches the research content of C?S bond cleavage and transformations.

The reactions of isomeric 1- and 3-arylsulfonyl-1-propynes and arylsulfonylallenes with primary aromatic amines in organic solvent-water system lead to arylsulfonyl-2-propanones.Unstable addition products (enamines) are formed in the reaction and then undergo hydration and are transformed into the ketones.
