Polyfluoroaromatic compounds play crucial roles in medicinal and material science. However, the synthesis of alkylated polyfluoroarenes has been relatively underdeveloped. In this study, we devised a novel decarboxylative coupling reaction between aliphatic N-hydroxyphthalimide esters and polyfluorostyrene, leveraging the photochemical activity of electron donor–acceptor (EDA) complexes. This method
多氟芳香族化合物在医学和材料科学中发挥着至关重要的作用。然而,烷基化多氟芳烃的合成还相对不发达。在这项研究中,我们利用电子供体-受体(EDA)复合物的光化学活性,设计了脂肪族N-羟基邻苯二甲酰亚胺酯和聚氟苯乙烯之间的新型脱羧偶联反应。该方法反应条件简单、底物范围广、官能团耐受性优异。此外,我们通过使用容易获得的羧酸作为起始材料对生物活性分子进行后期多氟芳基修饰,证明了该方案的实用性,从而为当前获取烷基化多氟芳基基序的工具箱提供了重要的补充。
