本文报道Cis-Pt(disphos)X_2系列化合物的~(13)C NMR研究。发现配体X、取代基R对桥环碳(C_1)化学位移有明显的影响;并证实了某些化合物象异构体的存在,还对构象特性进行了讨论。
This paper reports the ~ (13) C NMR studies of Cis-Pt (disphos) X_2 series of compounds. It was found that the ligand X and the substituent R have a significant effect on the chemical shift of the bridged carbon (C 1), and confirmed the existence of some compounds such as isomers. Conformational properties were also discussed.
