本文报道了两种膦功能化钳形N-杂环卡宾类似物[(PNNP)E](E=Ge，Sn)的合成和应用，以及它们对主族化合物和贵金属化合物的反应活性。这些柔性的四烯类配体具有不同寻常的配位几何结构和强烈的P-E相互作用，可扩展到与ECl2反应的二亚甲基或二茂铁化合物。这些化合物还成功地作为配体用于合成铜、银、金和铂的配合物。配体支架固有的灵活性使得金属中心的配位要求和金属间相互作用驱动了不同的结构安排。
We describe the synthesis and application of two phosphine-functionalized pincer-type N-heterocyclic carbene analogues [(PNNP)E] (E = Ge, Sn) and their reactivity toward main group and precious metal compounds. These flexible tetrelene ligands feature unusual coordination geometries and strong P-E interactions and are expandable to digermylene or distannylene compounds on reaction with ECl2. The compounds were also successfully applied as ligands for the synthesis of Cu, Ag, Au, and Pt complexes. The inherent flexibility of the ligand scaffold enabled different structural arrangements driven by the coordination requirements of the metal centers and intermetallic interactions.
