Abstract: A compound 2-(3-hydroxyphenyl)[60] fullerene pyrrolidine was synthesized by the 1,3-dipolar cycloaddition reaction of the fullerene(C60) and azomethine ylide (prepared from glycine and 3-hydroxybenzaldehyde). The product was characterized by UV-Vis,1H-NMR ,FT-IR and MS. The reaction conditions affecting the yields of product were investigated and the optimum reaction conditions with product yield 75% (based on consumed C60) were:molar ratio of C60∶3-hydroxybenzaldehyde:glycine 1∶3∶6,reaction temperature 95℃,reaction time 18h. DTA test showed good thermal stability of the product.

摘要: 利用甘氨酸和3-羟基苯甲醛与C60发生1, 3-偶极环加成反应,合成分离得到了2-(3-羟基苯基)[60]富勒烯吡咯烷,用UV-Vis、1H-NMR、FT-IR、MS等测试手段表征了产物的结构,并通过单因素方法,探讨了反应条件对产物产率的影响,得到最佳工艺条件:反应物摩尔比1∶3∶6, 温度95 ℃,反应时间18 h,产物的产率可达75%(以消耗的C60计)。利用差热分析仪测试了产物的热稳定性,结果表明,产物在空气中具有良好的热稳定性。
