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

Two types of oxygenative oxidations (Nucleophilic and Electrophilic Oxidations) of sulfur atom are proposed and a typical mode of nucleophilic oxidation is shown with a few unsymmetrical thiolsulfinates.

A facile synthesis of N-(carboselenoate) benzimidazolones through metal-free reactions of ortho-diisocyanoarenes with selenosulfonates is reported here. The desired products are obtained in moderate to good yields with good functional group compatibility. The ortho-diisocyanoarenes are applied to the construction of 2-benzimidazolone derivatives for the first time.
