  determined the crystal structure of this important starting material and found different ring sizes with dimeric versus trimeric formula units. The molecular shape depends on the polarity of the solvent used for recrystallization (n-pentane or 1,2-difluorobenzene). The synthesis of diphenylaluminum hydride, which is also long known in the literature, was optimized. It has a trimeric structure in the solid

  自 1988 年以来，二新戊基氢化铝 H-Al(CH2CMe3)2 的合成在文献中就已为人所知。我们确定了这一重要起始材料的晶体结构，并发现了具有二聚体与三聚体式单元的不同环大小。分子形状取决于用于重结晶的溶剂（正戊烷或 1,2-二氟苯）的极性。对文献中长期已知的二苯基氢化铝的合成进行了优化。它在固态时具有三聚体结构，带有一个 Al3H3 杂环。
• Al/P-Based Frustrated Lewis Pairs: Limitations of Their Synthesis by Hydroalumination and Formation of Dialkylaluminum Hydride Adducts

  Aluminum-phosphorus-based frustrated Lewis pairs (Al/P FLPs) are valuable reagents for the dipolar activation or coordination of small molecules or ionic compounds. They are accessible by hydroalumination of alkynylphosphines. However, as reported in this article, the application of this simple method for the synthesis of a broad variety of different compounds is limited to sterically shielded systems. Hydroalumination of Mes(2)PC CPh with small dialkyl- or diarylaluminum hydrides HAlR2 (R = Me, iBu, Ph) afforded unique adducts in which an HAlR2 molecule was coordinated by the Al/P FLP Mes(2)PC(=CHPh)AlR2 via an Al-P and an Al-H-Al 3c bond. A new Al/P FLP was obtained with equimolar quantities of dineopentylaluminum hydride. The less shielded alkynylphosphine Ph2PC CPh yielded a hydride adduct with HAlNp2 and an alkyne adduct with HAltBu(2). The latter compound resulted from triple-bond activation and had a five-membered AlPC3 heterocycle in which a C=C bond was bonded to the P and Al atoms of an Al/P FLP. Both compounds were isolated in high yields by application of the appropriate stoichiometric ratios of the starting materials.
