Abstract

The interaction of [(C₅H₄R)₂NdCl·2LiCl] (R = H, Bu^t) with one equivalent of Li[(CH₂(CH₂PPh₂] in refluxing tetrahydrofuran gave the purplish-blue complex [(C₅H₄R)₃NdCH₂P(Me)Ph₂] in 50% yield. The compounds have been carefully characterized by analytical, spectroscopic and X-ray diffraction methods. Variable temperature ³¹P{¹H} NMR spectroscopy indicated the existence of the following equilibrium: [(C₅H₄R)₃NdCH₂P(Me)Ph₂] + THF ⇌ (C₅H₄R)₃Nd(THF)+CH₂P(Me)Ph₂. At room temperature, the exchange between the coordinated and free ylide ligand is slow on the NMR time scale.
