Much attention has been drawn to the chemical derivatization of buckminsterfullerene, C_<60> in recent years. Among various reactions to be used for the functionalization of C_<60>, [2+1], [2+2], [2+3], [2+4] and [2+8] cycloaddition reactions have been successfully employed for preparation of the ring-fused C_<60> derivatives. In all cases, C_<60> acts as a dienophile. Meanwhile, photo-excited C_<60> is a strong electron acceptor and strained Si-Si and Ge-Ge s bonds can act as an electron donor. During the course of our research on chemical derivatization of fullerenes with organosilicon and -germanium compounds, we found that photochemical [2+3] cycloaddition of C_<60> and C_<70> with a disilirane and a digermirane take place and can demonstrate the intermediacy of an exciplex.

C_<60>巴克敏斯特富勒烯的化学衍生化是近年来研究的热点。在用于C_<60>功能化的各种反应中，[2+1],[2+2],[2+3]，[2+4]和[2+8]环加成反应已成功地用于制备环熔合C_<60>衍生物。在所有情况下，C_<60>作为亲二酚。同时，光激发C_<60>是强电子受体，应变Si-Si和Ge-Ge - s键可以作为电子给体。在研究富勒烯与有机硅和锗化合物的化学衍生化过程中，我们发现C_<60>和C_<70>与二硅烷和二硅烷发生了光化学[2+3]环加成，可以证明外络合物的中间性。
