Preparation and reactions of base-free bis(1,2,4-tri-tert-butylcyclopentadienyl)uranium oxide, Cp′2UO

Reduction of the uranium metallocene [η5-1,2,4-Me 3C)3C5H2]2UCl 2 (1), Cp′2UCl2, in the presence of 2,2′-bipyridyl and sodium naphthalene gives the dark green metallocene complex Cp′2U(bipy) (6), which reacts with p-tolyl azide or pyridine-N-oxide to give Cp′2U=N(p-tolyl) (7) or Cp′ 2U(O)(py) (8), respectively. The Lewis acid BPh3 precipitates Ph3B(py) and gives the base-free oxo Cp′ 2UO (10), which crystallizes from pentane. The oxometallocene 10 behaves as a nucleophile with Me3SiX reagents, but it does not exhibit cycloaddition behavior with acetylenes, suggesting that the polar resonance structure Cp′2U+-O- dominates the double-bond resonance structure Cp′2U=O.
