合成了一种新的二胺基铝配合物[{PhCH(CH_3)NHCH_2CH_2NCH(CH_3)Ph}AlMe_2],通过核磁和X射线单晶衍射技术对其结构进行了完全表征。该配合物能有效催化MPV反应,在无溶剂、催化剂用量摩尔比为5%、80℃反应5h的最优反应条件下,获得了一系列不同类型的一级和二级醇,产率为82%-99%。
A novel diamido aluminum complex [{PhCH (CH_3) NHCH_2CH_2NCH (CH_3) Ph} AlMe_2] has been synthesized and its structure has been completely characterized by single crystal X-ray diffraction and magnetic resonance spectroscopy. The complex can effectively catalyze the MPV reaction. A series of different primary and secondary alcohols were obtained under the optimal reaction conditions of no solvent, 5% molar ratio of catalyst and 5h reaction at 80 ℃. The yield was 82 % -99%.
