AuClL(1)/PdCl2L(2)2 cocatalyzed coupling of Ar(1)X and Ar(2)SnBu3 is feasible for bulky Ar(1), provided that at least one ligand on Pd is not strongly coordinating. This can be achieved in situ by Au/Pd ligand exchange if L(1) is weakly coordinating. When the exchange is slow, independent preparation of appropriate catalysts is recommended.
Au(1)/ PdCl2L(2)2的Ar(1)X和Ar(2)SnBu3的共催化偶联对于大体积的Ar(1)是可行的,前提是Pd上的至少一个
配体不是强配位的。如果L(1)弱配位,则可以通过Au / Pd
配体交换原位实现。当交换缓慢时,建议独立制备合适的催化剂。
