| 以石墨为原料通过Hummer化学氧化法制备出功能化氧化石墨材料,然后将手性二胺基团嫁接到氧化石墨上,再通过后修饰与金属铑配位制备出非均相催化剂,该催化剂在水介质中温和条件下对芳香酮的不对称氢转移反应显示出高的催化活性和对映选择活性. |

| Abstract: |
| Functional graphite oxide materials were synthesized through the Hummers chemical oxidation of graphite.Heterogeneous catalyst was prepared via direct grafting diamine-based chiral ligand to graphite oxide followed by the complexation with organorhodium complex.Such a chiral rhodium catalyst exhibited high catalytic activity and enantioselectivity in asymmetric transfer hydrogenation of aromatic ketones in aqueous medium under mild condition. |
| Key words: graphite oxide immobilization asymmetric transfer hydrogenation rhodium |
