资源简介：
The reactivity of alkylaluminum hydrides HAlMe2, HAl(CH2SiMe3)2, and H2AlMes* (Mes* = C6H2tBu3-2,4,6) toward yttrium methyl complexes was assessed. From the reaction with [Cp2YMe]2 the corresponding methylated alkylaluminum compounds could be isolated and characterized along with [Cp2Y(thf)(μ-H)]2, obtained upon workup in thf (Cp = C5H5 = cyclopentadienyl). Structurally characterized complexes Cp14Y6H3Cl and Cp15Y6H3 represent side-products of the transformation. The reactions of [YMe3]n and [(C5Me5)YMe2]3 indicated occurrence of hydrido transfer for H2AlMes* and led to product mixtures for HAl(CH2SiMe3)2. Following the reaction of HAlMe2 with these compounds as well as the half-sandwich derivatives (C5Me4R)Y(AlMe4)2 (R = Me, SiMe3) indicated reversible hydrido binding, leading ultimately to the formation of insoluble hydride clusters. The organoaluminum compounds [HAl(CH2SiMe3)2]3, [(μ-H)(Me)AlMes*]2, and Me2AlMes* were analyzed by X-ray crystallography.
