| Abstract: | 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)2Yb(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. |
