以白色磷（P-4）为原料直接合成有机磷化合物具有重要意义，因为该工艺避免了工业合成方法的污染，为许多新型含磷化合物的合成提供了可能。从环戊二烯的P-4功能化反应中合成了一个三核稀土金属配合物[{（eta（5）-C5 Me 5）LuCl}（3）（THF）P-6][Li（THF）（4）]。该配合物含有一个未见报道的双环[3.1.0]-P-6（4-）配体。X射线衍射分析表明，双环[3.1.0]-P-6（4-）配体呈船形构象。三个镥原子分别以eta（1），eta（3），eta（3）模式与该配体配位，形成了一个新的[P6 Lu 3]笼。密度泛函理论（DFT）计算表明，有两个三中心两电子键。
Direct synthesis of organophosphorus compounds from white phosphorus (P-4) is of great significance because this process avoids the industry pollution synthetic methods and provides the possibilities for many novel phosphorus-containing compounds. A trinuclear rare-earth metal complex [{(eta(5)-C5Me5) LuCl}(3)(THF)P-6][Li(THF)(4)] from lutetacyclopentadiene mediated P-4 functionalization was isolated and characterized. This novel complex contains a bicyclo[3.1.0]-P-6(4-) ligand which is an unreported type. X-ray diffraction analysis shows that the bicyclo[3.1.0]-P-6(4-) ligand adopts a boat-like conformation. Three lutetium atoms coordinate to this ligand in eta(1), eta(3), eta(3) mode, respectively, and a novel [P6Lu3] cage has been formed. Density functional theory (DFT) calculations indicate that there are two three-center two-electron bonds.
