摘要: The reaction of [LAlH2] (L=HC(CMeNAr)2, Ar=2,6-iPr2C6H3) with MeOTf (Tf=SO2CF3) resulted in the formation [LAlH(OTf)] (1) high yield. triflate substituent 1 increases positive charge at aluminum center, which implies that has a strong Lewis acidic character. excellent catalytic activity for hydroboration organic compounds carbonyl groups was investigated. Furthermore, it shown effectively initiates addition trimethylsilyl cyanide (TMSCN) to both aldehydes and ketones. Quantum mechanical calculations were carried out explore mechanism.
