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.
