通过膦胺Ph（2）PNHAd与（Me_3SiCH_2）（3）Ln（THF）（2）和（Ph_3P）（4）Pd或（COD）Pd（CH_2SiMe_3）（2）的顺序反应，合成了一系列具有Pd -> Ln（Ln = Sc，Y，Yb，Lu）配位键的Pd-Ln杂环配合物。这些配合物通过NMR光谱、X射线衍射、计算以及电化学研究进行表征，其揭示了Pd -> Ln配位相互作用根据Ln（3+）的离子半径而变化。此外，还研究了Pd-Ln配合物在溶液中的动力学结构特征及其对卤代芳烃和乙烯酮的类刘易斯对反应性。
A series of heterobimetallic Pd-Ln complexes with Pd -> Ln (Ln = Sc, Y, Yb, Lu) dative bonds were synthesizedviasequential reactions of phosphinoamine Ph(2)PNHAd with (Me3SiCH2)(3)Ln(THF)(2) and (Ph3P)(4)Pd or (COD)Pd(CH2SiMe3)(2). These complexes were characterized by NMR spectroscopy, X-ray diffractions, and computational as well as electrochemical studies, which revealed Pd -> Ln dative interactions that vary according to the ionic radii of Ln(3+). Furthermore, the notable dynamic structural features of the Pd-Ln complexes in solution and their unexpected frustrated Lewis pair-like reactivity toward aryl halides and ketene were also studied.
