Nickel‐Catalyzed Deaminative Cross‐Coupling of Disulfides with Katritzky Pryidium Salts to Construct Sulfides

Abstract The synthesis of thioether or selenoether through the cross‐coupling of C−S or C−Se bond is a high attractive research area due to the prevalence of thioether or selenoether in pharmaceutically active compounds, bioactive natural compounds, agrochemicals, and functional materials. Herein, a novel and general method has been developed for the construction of C−S or C−Se bonds using Katritzky pyridinium salts with disulfides or diselenides in the presence of nickel catalyst. This procedure exhibits remarkable functional group tolerance. Under mild reaction condition, a variety of thioethers and selenoethers is successfully and efficiently obtained through deaminative cross‐coupling.
