| 摘 要： | 研究了双-(3-二苯基膦丙基)苯基膦铑氯化物Rh(ttP)Cl在不同溶剂中的31PNMR谱。结果表明,该络合物在二氯甲烷或氯仿中的化学位移和耦合常数发生很大改变,而在乙腈、DMF、DMSO等溶剂中则无变化,推测二氯甲烷和氯仿作为Lewis酸和Rh(ttp)Cl反应,生或新络合物,建议在研究金属络合物x-射线衍射结构和NMR数据相关性时应避免使用二氯甲烷和氯仿。

| Abstract: | ~(31)P NMR spectrum of bis - ( 3 -diphenylphosphinopropyl) -phenylphosphinerhodium chloride Rh (ttp) Cl in different solvents were studied. It was found that in methylene chloride and chloroform Rh (ttp) Cl has dramatically different chemical shifts and coupling constants, whereas solvents CH_3CN, DMF, DMSO do not react with Rh(ttp) Cl. It was suggested that methylene chloride and chloroform act as Lewis acid with Rh(ttp)C1. We suggest that methylene chloride and chloroform be avoided when one wants to draw correlations between X-ray structure and XMR data of metal complexes. |
