Fgn. Cloke et al., SYNTHESIS OF TRIS(TETRAMETHYLCYCLOPENTADIENYL) DERIVATIVES OF THE ACTINIDE METALS - MOLECULAR-STRUCTURE OF [UCL(ETA-C5ME4H)3], Organometallics, 13(7), 1994, pp. 2895-2897
The reaction of [Li(C5Me4H)] with MCl4 (M = U, Th) in tetrahydrofuran
gives highly sterically congested tris(tetramethylcyclopentadienyl)act
inide(IV) derivatives which have been characterized by variable-temper
ature NMR studies and, in the case of the uranium compound, by X-ray c
rystallography.
