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. A graphene hybrid (Lys-GO) was prepared by L-lysine-modified graphene oxide (GO), which was used as a solid ligand for Cu-catalyzed C-N coupling reactions. Alkali and temperature on the reaction.In the presence of NaOH in the presence of NaOH in the presence of NaOH at 100 ℃, a series of aryl compounds and aza compounds were coupled with the help of cuprous iodide to obtain medium and above yields.In addition, The catalytic system solves the problems of difficult separation and difficult recycling of the homogeneous catalyst and the product, reduces the cost of the catalyst and reduces the environmental pollution.
