The development of selective synthetic method of mono- and bis-functionalized fullerene derivatives for high-performance plastics

以对甲苯磺酰肼为原料，在双水相体系中合成了甲基富勒烯，如[6，6]-苯基-C_(61)-丁酸甲酯及其衍生物。该反应条件成功地应用于微反技术，获得了较高的单加合物选择性。我们还发现了在1，8-二氮杂双环-[5.4.0]Undec-7-ene(DBU)存在下，富勒烯与硫叶立德衍生物在室温下反应，以较高的产率直接合成PCBM的方法。该方法还成功地应用于高α选择性的[6，6]-苯基-C；71&gt；-丁酸甲酯的合成。

Methanofullerenes, such as [6,6]-phenyl-C_<61>-butyric acid methyl ester (PCBM) and its derivatives were synthesized in ood yields from corresponding tosylhydrazones in an aqueous two-phase system. This reaction condition was successfully applied for the microreactor technology to obtain higher selectivity for the monoadducts. We also found the methodology to synthesize PCBM directly in good yields, by the reaction of fullerene with sulfur ylide derivatives in the presence of 1,8- diazabicyclo- [5.4.0]undec-7-ene (DBU) at room temperature. This method was also successfully applied to the preparation of [6,6]-phenyl- C_<71>-butyric acid methyl ester ([70]PCBM) with high α-selectivity.
