Exploiting Trans‐Sulfinylation for the Synthesis of Diverse N‐Alkyl Sulfinamides via Decarboxylative Sulfinamidation

Combining simple amines with the bench‐stable sulfinylamine Tr‐NSO allows in situ preparation of reactive alkyl sulfinylamines, which when combined with alkyl radicals generated by photocatalytic decarboxylation, provides N‐alkyl sulfinamides. The reactions are broad in scope and tolerate a wide variety of functional groups on both the acid and amine components. The sulfinamide products are used to prepare a selection of challenging S(VI) products. The method provides a convenient way to use reactive and unstable alkyl sulfinylamines.
