The interaction of [(η5-C5H4But)2YbCl · LiCl] with one equivalent of Li[(CH2) (CH2)PPh2] in tetrahydrofuran gave [Ph2PMe2] [(η5-C5H4But)2Li] (1) and [(η5-C5H4But)2 Yb(Cl)CH2P(Me)Ph2] (2) in 10% and 30% yields, respectively. 1 could also be prepared in 70% yield from the reaction of [Ph2PMe2][CF3SO3] with two equivalents of (C5H4But)Li. Both compounds have been fully characterized by analytical, spectroscopic and X-ray diffraction methods. The solid state structure of 1 reveals a sandwich structure for the [(η5-C5H4But) 2Li]-anion.
