报道了膦酰氨基硅烷SiNP配体的铑配合物的合成。母体（SiNP）H配体（4）与0.5当量的（SiNP）H配体（4）反应。[（COE）RhCl]2（COE =顺式环辛烯）在NaN（SiME 3）2存在下导致（SiNP）Rh（COE）（5）的形成。通过用相应的亚磷酸酯处理，将化合物5转化为一系列（SiNP）Rh（P（OR）3）络合物6-10（R = Ph、iPr、nBu、Et或Me）。NMR和XRD结构数据以及DFT计算分析表明，化合物5-10分为两种结构类型（A和B），不同的是SiNP配体的Si-H键与Rh的相互作用的性质。
Syntheses of Rh complexes of the phosphine-amido-silane SiNP ligand are reported. The reaction of the parent (SiNP)H ligand (4) with 0.5 equiv. [(COE)RhCl]2 (COE = cis-cyclooctene) in the presence of NaN(SiME3)2 resulted in the formation of (SiNP)Rh(COE) (5). Compound 5 was converted to a series of (SiNP)Rh(P(OR)3) complexes 6–10 (R = Ph, iPr, nBu, Et, or Me) by treatment with the corresponding phosphite. NMR and XRD structural data, as well as the DFT computational analysis indicate that compounds 5–10 are divided into two structural Types (A and B), differing in the nature of the interaction of the Si–H bond of the SiNP ligand with Rh.
