A series of homoleptic rare earth (RE) complexes bearing phosphino-aryloxide ligands (, ) has been prepared. The complexes have been characterised using multinuclear NMR and IR spectroscopy, X-ray crystallography and elemental analysis. Structural characterisation highlighted the different RE-P interactions as a result of differing Lewis acidity and ionic size across the series, hinting at the possibility of FLP-type activity. The potential reactivity of these complexes has been tested by reacting them with small molecules (H, CO, CO). A series of side-products () has also been observed, isolated and characterised, featuring the incorporation of a phosphonium-aryloxide ligand.
已制备出一系列带有膦基芳氧基配体(,)的均配稀土(RE)配合物。这些配合物已通过多核NMR和IR光谱、X射线晶体学和元素分析进行了表征。结构表征突出了由于该系列中不同的路易斯酸度和离子尺寸导致的不同的RE-P相互作用,暗示了FLP型活性的可能性。这些配合物的潜在反应性已通过使其与小分子(H、CO、CO)反应进行了测试。还观察、分离和表征了一系列副产物(),其特征是引入了鏻基芳氧基配体。
