The aluminum analogue of Piers' borane, [HAl(CF)]1, is prepared on a gram-scale. Density functional theory (DFT) calculations reveal 1 has a higher fluoride ion affinity (FIA) than Piers' borane, while the Al-H moiety proved to be a strong hydride donor, reacting with alcohol and terminal alkyne to give the corresponding dehydrogenative products 3 and 4. Hydroalumination product 5 was prepared reaction of 1 with aldehyde. In addition, 1 catalyzes the hydrosilylation of alkynes and alkenes.
皮尔斯硼烷的铝类似物[HAl(CF)]1是以克级规模制备的。密度泛函理论（DFT）计算表明，1比皮尔斯硼烷具有更高的氟离子亲和力（FIA），而Al-H部分被证明是一种强氢化物供体，能与醇和末端炔烃反应生成相应的脱氢产物3和4。通过1与醛的反应制备了氢化铝产物5。此外，1催化炔烃和烯烃的硅氢化反应。
