| 摘 要： | 采用自由配体法将(1S,2S)-DPEN(1,2-diphenyl-1,2-ethylene-diamine)-Ru(TPP)2(TPP=三苯基膦,triphenylphosphine)配合物封装于NaY沸石分子筛超笼中,制备了(1S,2S)-DPEN-Ru(TPP)2/Y主客体材料(1S,2S)-DPEN=1,2-二苯基-1,2-乙二胺).采用等离子体发射光谱ICP、粉末X射线衍射(XRD)、紫外光谱(UV-Vis)、氮吸附等物理化学手段对所制备材料进行了表征.结果表明,(1S,2S)-DPEN-Ru(TPP)2配合物封装于Y型分子筛超笼中保持了原有的物理化学性能;作为苯乙酮不对称加氢催化剂,在优化条件下,苯乙酮的转化率可达100%,(R)-苯乙醇的对映体过量值(ee值)可达61.0%.该催化剂具有良好的稳定性和重复使用性. |

| Abstract: | (1S,2S)-DPEN(1,2-diphenyl-1,2-ethylene-diamine)-Ru(TPP)2(TPP=triphenyl-phosphine) was encapsul-ated in the supercage of zeolite Y by the flexible ligand method, and characterized by ICP, XRD, UV-Vis, Low temperature N2 adsorption and desorption. The results showed that the(1S, 2S)-DPEN-Ru(TPP)2((1S, 2S)-DPEN=meso -1,2-Diphenylethylenediamine) was formed in the supercage of zeolite Y. As an asymmetric hydrogenation catalyst, the conversion of acetophenone and the enantiomeric excess value(ee value) of (R)-phenylethanol achieved 100% and 61.0%, respectively. The catalyst is with high stability and repeatability in the reaction without loss of activity and ee value. |
