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.
