空富勒烯与二硅烷（1）和二锗烷（2）的热反应得到相应的双甲硅烷基化和双锗烷基化衍生物。当双环稠合硅烷（3a）在C70存在下加热时，通过热挤出甲硅烯得到两种甲硅烯加合物。这些结果提供了一个补充的方法，反应性硅和锗化合物，这已被长期用于富勒烯的衍生化的光化学加成。电化学分析表明，硅烷基化和锗烷基化的C70的氧化还原性能，表明硅烷基和锗烷基基团引入的富勒烯笼所造成的电子扰动。理论计算也进行了理解的富勒烯衍生物的电子性质。
Thermal reactions of empty fullerenes with disilirane (1) and digermirane (2) afforded the corresponding bis‐silylated and bis‐germylated derivatives. When a bicyclic fused silirane (3a) was heated in the presence of C70, two silylene adducts were obtained through thermal extrusion of silylenes. These results provide a complementary method to the photochemical addition of reactive silicon and germanium compounds, which have been long employed for derivatization of fullerenes. Electrochemical analyses revealed the redox properties of the silylated and germylated C70, indicating the electronic perturbation caused by silyl and germyl groups introduced on the fullerene cages. Theoretical calculations were also conducted for understanding of the electronic property of the fullerene derivatives.
