thermal Mizoroki-Heck reaction and Suzuki coupling giving high yields in short reaction times. A thermal redox mechanism probably occurs whereby Ni complex transfers electron and reduces the Pd (II) to Pd (0) which then takes the reactants through the standard protocol of oxidative-addition, migratory insertion and reductive elimination, typical for the Mizoroki-Heck reaction and the Suzuki coupling
Pd 和 Ni 配合物的组合激活了芳基溴化物,用于热 Mizoroki-Heck 反应和 Suzuki 偶联,在短反应时间内获得高产率。可能会发生热氧化还原机制,Ni 配合物转移电子并将 Pd (II) 还原为 Pd (0),然后将反应物带入氧化加成、迁移插入和还原消除的标准方案,这在 Mizoroki-Heck 反应中很典型和铃木联轴器。
