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.

吡咯烷的脱氢芳香化和磺酰化：在光氧化还原催化中的正交反应性。

建立了可见光氧化还原催化下N-杂环的氧化脱氢芳构化和选择性磺酰化反应。温和的反应条件使该方法成为使吡咯烷官能化/氧化的引人入胜且通用的策略，由此鉴定出芳基磺酰氯既是催化剂再生又是磺酰化试剂。
