Elution of compounds [PdCl3-ClC6H3CHNCH(Me)Ph}trans-2-PPh2(CyOH)}] 5a and [PdXC6H4CH(Me)NH2}Ph2PCH(OMe)Ph}] 6b, containing the racemic phosphines as ligands, through a SiO2 column allows the separation of the two diastereoisomers. Optically active coordination complexes trans-[PtCl2Ph2PCH(OMe)Ph}2] and trans-[PtCl2Ph2PCH(OMe)Ph}(PPh3)], have been obtained by ligand transfer reactions between
化合物[PdCl 3-ClC 6 H 3 CH NCH(Me)Ph} 反式2-PPh 2(CyOH)}] 5a和[PdX C 6 H 4 CH(Me)NH 2 } Ph 2的洗脱含有外消旋膦作为配体的PCH(OMe)Ph}] 6b通过SiO 2色谱柱可以分离两种非对映异构体。光学活性配位化合物反式-[PtCl 2 Ph 2 PCH(OMe)Ph} 2 ]和反式-[PtCl 2 Ph 2 PCH(OMe)Ph}(PPh 3)]分别通过6b与PtCl 2或反式[PtCl(μ-Cl)(PPh 3)] 2之间的配体转移反应获得。可以从铂化合物中分离出双核环palpalated拆分剂,并将其用于新的拆分过程中。
