Aromatic compounds interact with organozinc reagents under photoredox conditions, leading to the substitution products. The reaction is performed under blue light irradiation via in situ generated organozinc reagents (Barbier conditions), which are oxidized by the photocatalyst, followed by radical attack at the aromatic substrate. The method works with polyfluorinated arenes, 2-chlorobenzoxazoles
芳香族化合物在光氧化还原条件下与有机锌试剂相互作用,产生取代产物。该反应在蓝光照射下通过原位生成的有机锌试剂(巴比尔条件)进行,该试剂被光催化剂氧化,然后对芳香族底物进行自由基攻击。该方法适用于多氟化芳烃、2-氯苯并恶唑和2-磺酰基取代的苯并噻唑。
