亚甲基[6,6]-富勒烯[C_(60)]单羧酸的合成

Synthesis of methano[6,6]fullerene[C_(60)]carboxylic acid

目的:探索用溴乙酸乙酯合成亚甲基[6,6]-富勒烯[C60]单羧酸。方法:用溴乙酸乙酯制备硫叶立德,再与富勒烯[C60]制得相应的富勒烯[C60]羧酸乙酯,水解其乙酯。结果与结论:通过核磁、红外等分析方法确证所合成的中间体和目标化合物,并且这条路线经济、切实可行,适合大规模制备。

Objective ： To find good route of synthesizing methano [ C60 ] fullerene carboxylic acid by using bromoactate for preparing some valuable fullerene derivatives. Methods： Using bromoactate as starting material, ylide was prepared. Ylide and fullerene were used to produce the methano [ C60 ] fullerene carboxylate and hydrolyze it. Results and Conclusion： The intermediate and ultimate products synthesized can be confirmed as the objective by NMR and IR, the method is feasible and economical .
