The photocycloaddition of vinylcyclopropanes to C60 yields stereospecifically a five-membered [60]fullerene adduct. These results suggest a biradical intermediate of the [2 + 2] photocycloaddition between dienes or arylalkenes and C60. An electron transfer between the triplet excited state of C60 and the unsaturated substrates precedes the formation of the intermediate.
乙烯基环丙烷与C60的光环加成反应立体专一性地生成一种五元[60]富勒烯加合物。这些结果表明，二烯或芳基烯烃与C60之间的[2 + 2]光环加成反应存在双自由基中间体。在中间体形成之前，C60的三重激发态与不饱和底物之间发生了电子转移。
