N‐aryl/benzoyl acrylamides have been established through visible‐light‐enabled photocatalysis, furnishing a wide variety of functionalized oxindoles and isoquinolinediones in good‐to‐excellent yields under the synergistic interactions of an organic fluorophores‐type photocatalyst 4CzIPN, trifluoroacetoxyiodobenzene (PIFA), and 1,3,5‐trimethoxybenzene with visible light irradiation. The prominent features of this
N-芳基/苯甲酰基丙烯酰胺的自由基级联氧化烷基芳基化是通过可见光光催化建立的,在有机荧光团型光催化剂4CzIPN的协同作用下,提供了多种功能化的羟吲哚和异喹啉二酮,具有良好至优异的收率。 ,三氟乙酰氧基碘苯(PIFA)和1,3,5-三甲氧基苯在可见光下照射。该方法的突出特点是广泛的底物范围,出色的官能团耐受性和温和的反应条件。
