| 中文摘要: |
| 通过L-赖氨酸修饰氧化石墨烯(GO)制备了一种石墨烯杂化材料(Lys-GO). 该材料作为一种固体配体用于铜催化的C-N偶联反应. 考察了碱和温度对反应的影响. 在100℃氮气气氛中，NaOH存在下，该固体配体辅助碘化亚铜催化一系列芳基化合物和氮杂化合物偶联，达到中等及以上收率. 另外, 该催化体系解决了均相催化剂和产品的分离困难和难循环使用的问题，降低了催化剂成本，减少了环境污染. |
| 英文摘要: |
| A graphene hydrid material (Lys-GO) was prepared by L-lysine grafted on the graphene oxide. The Lys-GO materials can be used as heterogeneous ligands for CuI catalyzed C-N coupling reactions. The effects of base and temperature on the reaction were investigated. The desired products were obtained with good yields at 100 ℃ under N2 atmosphere with KOH as base. Additionally, this catalyst system resolved the problem which homogeneous catalysts are difficult to be separated from the reaction product and recycled, which reduced the cost of catalyst and the release of environment pollutions. |
