Schneider, Jörg J. | Specht, Ullrich
The title compound [(η⁵-tBu₃Cp)CoBr]₂ 1 is prepared in a one pot reaction starting from 1,2,4- tBu₃-cyclopentadiene followed by metallation and by reaction of the resulting tBu₃Cp⁻K⁺ anion salt with anhydrous CoBr₂ in THF. 1 was isolated from this reaction in 78% yield as black crystals. 1 reacts with LiAlH₄ in THF at 0 °C. Subsequent alcoholysis of the crude reaction mixture with ethanol at -78 °C gives the novel trihydride cluster [(η⁵-tBu₃Cp)Co]₂H₃ 2 in 58% isolated yield as black crystals. 2 has been characterized by ¹H NMR, ESR, MS, and IR spectroscopy, as well as by elemental analysis.
