想问下Pd(dba)2 和 Pd2(dba)3有什么区别,为什么Pd2(dba)3有多个CAS号?Pd(dba)2 is formulated more correctly as Pd2(dba)3·dba, in which the binuclear complex consists of two Pd atoms bridged by three dba molecules via the C=C olefin portions and the last dba does not coordinate to the Pd center (J. Chem. Soc., Chem. Commun. 1970, 1065; J. Organomet. Chem. 1974, 65, 253). The main difference between Pd2(dba)3 and Pd(dba)2 is the Pd/dba stoichiometry, 这是查了一个文献的结果,Org. Lett. 2014, 16, 4074−4077 另外做Miyaura硼酸酯一般用Pd(dppf)Cl2,需要用Pd2(dba)3吗查看更多
