Cerium Aryloxides as Precursors for Monopentamethylcyclopentadienyl Organocerium(III) Compounds; X-Ray Crystal Structure of (ν5-Pentamethylcyclopentadienyl)bis(2,6-di-t-butylphenoxo)cerium

Tris(2,6-di-t-butylphenoxo)cerium reacts with (C5Me5)Li in pentane to form (ν5-C5Me5)bis(2,6-di-t-butylphenoxo)cerium, whose structures was established by X-ray crystallography and which, on subsequent reaction with LiCH(SiMe3)2, gives a novel mono(C5Me5)cerium-bisalkyl complex, (C5Me5)Ce2.

First example of a neutral homoleptic uranium alkyl. Synthesis, properties, and structure of U[CH(SiMe3)2]3

The reaction of U(O-2,6-But2C6H3)3 with 3 equiv of LiCH(SiMe3)2 in hexane at ambient temperature provides royal blue U[CH(SiMe3)2]3 (1) in ca. 40% isolated yield. In the solid state, 1 is pyramidal with crystallographically imposed C3 symmetry, a U(1)-C(4) (i.e., U-Cα) bond length of 2.48 (2) A?, and a C(4)-U(1)-C(4′) bond angle of 107.7 (4)°. The molecular structure also features a γ-agostic interaction with three symmetry-related silyl methyl groups [U(1)-C(7) = 3.09 (2) A?]. 1 is thermally stable as a solid at room temperature but decomposes with loss of H2C(SiMe3)2 at ca. 60°C. Solutions of 1 in hexane or THF slowly decompose over the course of several hours. Reaction of UCl3(THF)x with 3 equiv of LiCH(SiMe3)2 in THF does not produce U[CH-(SiMe3)2]3 but rather a green ionic complex of formula [Li(THF)3] [UCl{CH(SiMe3)2}3].
