A novel, Pd-catalyzed oxidative Heck reaction of non-activated alkenes synergistically directed by bifunctional groups has been developed firstly by using O2 as a green oxidant, yielding the oxidative Heck products with excellent yields in a regio- and stereoselective manner. This bifunctional synergistic activation mechanism was demonstrated by experimental analysis and detailed computational studies
通过使用 O 2作为绿色氧化剂,首先开发了一种由双官能团协同引导的新型 Pd 催化的非活化烯烃的氧化 Heck 反应,以区域选择性和立体选择性的方式产生具有优异产率的氧化 Heck 产物。通过实验分析和详细的计算研究证明了这种双功能协同激活机制,其中羟基指导烯烃的迁移插入,三氟甲基促进随后的 β-H 消除和还原消除。此外,以双功能协同定向C-H芳基化为关键步骤合成了一种杀虫活性化合物,证明了其合成实用性。
