Heterogeneous Ru(II)-NH-propyl-(1R,2S)-(+)-cis-1-amino-2-indanol as chiral catalyst for asymmetric transfer hydrogenation reaction of prochiral ketones |
| 초록 |
The novel NH-propyl-(1R,2S)-(+)-cis-1-amino-2-indanol was immobilized over mesoporous siliceous SBA-15 by a step by step post synthesis modification method. The chiral heterogeneous catalysts were synthesized by complexation by [RuCl2(benzene)]2 and [RuCl2(p-cymene)]2 in 2-propanol at reflux condition. The synthesized heterogeneous materials were characterized by SAXS, FT-IR, ICP-AES, Diffuse reflectance UV-Vis, XPS, 29Si and 13C CP MAS-NMR spectroscopic analyses, N2 adsorption-desorption isotherms, SEM and TEM. Further the synthesized materials were successfully applied in the asymmetric transfer hydrogenation reaction (ATH) of simple prochiral ketones. The reactions demonstrated high catalytic activities and excellent enantioselectivities for most simple aromatic ketones. In particular, these heterogeneous catalysts can be readily recovered and used in multiple consecutive catalytic runs and generally showed approximately the same enantiomeric excess values at lower conversions. |
