Abstract: | The reaction of Ln(AlMe(4))(3) with bulky hydrotris(pyrazolyl)borate (Tp(t)(Bu,Me))H proceeds via a sequence of methane elimination and C-H bond activation, affording unprecedented rare-earth metal ligand moieties including Ln(Me)(micro-Me)AlMe(3)] and X-ray structurally characterized "Tebbe-like" Ln(micro-CH(2))(2)AlMe(2)]. |
