  Synthesis and Properties of a Rhodium Complex Having a Novel β-Ketophosphenato Ligand, a Heavier Congener of a β-Ketoiminato Ligand

  摘要：

  The first stable rhodium complex having a beta-ketophosphenato ligand, which is a heavier congener of a beta-ketoiminato ligand, has been synthesized and characterized. Comparison of properties between rhodium beta-ketophosphenates 2 and rhodium beta-ketoiminate 4 revealed the unique character of the beta-ketophosphenato ligand, where the trans influence of the phosphorus atom should be stronger than the nitrogen atom of the beta-ketoiminato ligand.

  A novel β-ketophosphenato ligand bearing a bulky substituent, Tbt(2,4,6-tris[bis(trimethylsilyl)methyl]phenyl), on the phosphorus atom was newly designed and synthesized as a heavier congener of a β-ketoiminato ligand. Rhodium and iridium complexes bearing this new β-ketophosphenato ligand have been synthesized and fully characterized by spectroscopic and elemental analyses together with X-ray crystallographic

  新型设计和合成了一种新型的β-酮膦酸酯配体，该配体在磷原子上带有一个大的取代基Tbt（2,4,6-三[双（三甲基甲硅烷基）甲基]苯基]，它是β-酮亚胺配体的较重同类物。合成了带有这种新的β-酮膦酸根配体的铑和铱配合物，并通过光谱和元素分析以及X射线晶体学分析对其进行了全面表征。NMR光谱研究和X射线结构分析的结果表明，由于低配位的磷原子，β-酮膦酸根配体具有独特的电子特征。β-酮基次膦酸铑2a和b与β-酮基铑7的性质比较 揭示了β-酮基磷酸酯配体的特征，其中磷原子的反式影响应强于β-酮基氨基配体的氮原子。
