Oxidative dehydrogenative aromatization and selective sulfonylation reactions of N-heterocycles under visible-light photoredox catalysis were established. The mild reaction conditions make this approach an appealing and versatile strategy to functionalize/oxidize pyrrolidines whereby arylsulfonyl chlorides were identified to be both catalyst regeneration and sulfonylation reagents.
