supported 1,2-diaminocyclohexane Pd-complex (100–500 mol ppm of Pd) was found to be an efficient catalyst in the palladium-catalyzed Mizoroki–Heck, Suzuki–Miyaura and copper-free Sonogashira cross-coupling reactions of aryl halides under mild reaction conditions. The Pd-complex efficiently promoted all of these coupling reactions with appropriate coupling partners to afford the corresponding coupling products

1,2-二氨基环己烷Pd络合物(100-500 mol ppm Pd)是
钯催化的Mizoroki-Heck,Suzuki-Miyaura和无
铜Sonogashira交叉偶联反应的有效催化剂。芳基卤化物在温和的反应条件下。Pd-配合物可以通过适当的偶合剂有效地促进所有这些偶合反应,从而以几乎定量的产率提供相应的偶合产物。负载的
钯络合物很容易被回收并使用五次,而其催化活性没有明显损失。
