本文报道了一种新的捕获在六元富电子骨架中的氮杂环膦阳离子的合成和表征。该阳离子与1当量的威尔金森催化剂Rh（PPh 3）3 Cl定量反应，形成阳离子铑-膦络合物，这是第一个以固态表征的。计算和X射线衍射研究支持铑和磷之间存在强dπ-pπ键。
The synthesis and characterization of a new N-heterocyclic phosphenium cation captured in a six-membered, electron-rich framework is presented. The cation reacts quantitatively with 1 equiv of Wilkinson's catalyst, Rh(PPh 3 ) 3 Cl, to form a cationic rhodium-phosphenium complex, the first to be characterized in the solid state. Computational and X-ray diffraction studies support the existence of a strong dπ-pπ bond between rhodium and phosphorus.
