single‐step synthesis, coordination behavior, and application of a bis(phosphite) ligand in the isomerizing hydroformylation of internal olefins was investigated. Interestingly, high‐pressure NMR spectroscopy investigations revealed unexpected inequivalency of the two phosphorus nuclei, which display bisequatorial coordination of the bis(phosphite) ligand in a trigonal bipyramidal rhodium complex.

研究了单(亚磷酸酯)配体的单步合成,配位行为及其在内烯烃异构化加氢甲酰化中的应用。有趣的是,高压NMR光谱研究揭示了两个磷核的意料之外的不等价性,它们显示了三角双锥体铑络合物中双(亚磷酸酯)配体的双谱位配位。在使用极富挑战性的植物油衍生的底物油酸甲酯进行异构化加氢甲酰化后,双(亚磷酸酯)铑络合物显示出前所未有的75%的线性选择性。
