We
describe reactions of the dilithioallene precursor Li2(Me3SiC3SiMe3) (1)
with Cp2HfCl2, which depending on the stoichiometric
ratio furnishes either a highly sensitive dinuclear allenediide bridged
hafnocene dichloride complex (2-Hf) or a chemically robust
dihafnacyclooctatetraene (3-Hf). Both complexes were
fully characterized, and their formation was analyzed by in
situ NMR spectroscopy. Other than that described before for
the Zr analogues, the generation of both isolated complexes occurs
via a Li containing, yet structurally elusive, metallocene intermediate.
