reaction of [LAlH2] (L=HC(CMeNAr)2, Ar=2,6‐iPr2C6H3) with MeOTf (Tf=SO2CF3) resulted in the formation of [LAlH(OTf)] (1) in high yield. The triflate substituent in 1 increases the positive charge at the aluminum center, which implies that 1 has a strong Lewis acidic character. The excellent catalytic activity of 1 for the hydroboration of organic compounds with carbonyl groups was investigated. Furthermore
[LAlH 2 ](L = HC(CMeNAr)2,Ar = 2,6 - i Pr 2 C 6 H 3)与MeOTf(Tf = SO 2 CF 3)的反应导致[LAlH(OTf)的形成](1),高收率。在三氟甲磺酸酯取代基1增加了在铝中心,这意味着正电荷1具有很强的路易斯酸性字符。研究了1对具有羰基的有机化合物进行氢硼化的优异催化活性。此外,显示出1有效地引发三甲基甲硅烷基氰化物(TMSCN)与醛和酮的加成反应。进行了量子力学计算以探索反应机理。
