We have developed effective reaction conditions for the ­Suzuki cross-coupling of chlorinated hexaphenylbenzene derivatives. A chloro group on a hexaphenylbenzene framework exhibits a low reactivity to Suzuki cross-coupling, and only nickel catalysts bearing alkyl-substituted phosphine ligands achieved the coupling. With this as a key step, we succeeded in the selective preparation of a C 2 v -symmetric hexaphenylbenzene derivative containing two kinds of aryl group.

通过顺序 Suzuki 偶联选择性制备 C 2v -对称六苯基苯衍生物

我们已经为氯化六苯基苯衍生物的 Suzuki 交叉偶联开发了有效的反应条件。六苯基苯骨架上的氯基团对 Suzuki 交叉偶联的反应性较低，只有带有烷基取代膦配体的镍催化剂才能实现偶联。以此为关键步骤，我们成功地选择性制备了含有两种芳基的C 2 v 对称六苯基苯衍生物。
