| Abstract: | Dicyclopentadienyl-η1-cyclooctatrienyltitanium and -η3-cyclooctatrienylniobium are prepared from (C5H5)2MCl2 (M = Ti, Nb) and two equivalent amounts of i-PrMgCl in the presence of an excess of cyclooctatetraene. For the preparation of (C5H5)2NbC8H9 the presence of NaBH4 is also necessary. The products obtained are characterized by IR, mass and 1H NMR spectroscopy. Reactions with HCl, thermal decomposition reactions, magnetic measurements and elemental analyses were performed to establish the structures. |
