Palladium-Catalyzed Coupling of Aryl Iodides with Sulfinamide Reagents for the Construction of Sulfinamides.

A novel sulfinamide reagent was developed that enables the one-step installation of sulfinamides through palladium-catalyzed coupling with aryl iodides. This method offers distinct advantages, including the use of readily available starting materials and broad substrate compatibility. Moreover, the strategy was successfully extended to the synthesis of complex functional molecules. Mechanistic investigations reveal that the key intermediate undergoes base-promoted retro-Michael addition to afford the target product.
