[reaction: see text] The photocycloaddition of dienyl cyclopropanes to C(60) gives a new synthetic approach to yield stereospecifically five-, seven-, and nine-membered [60]fullerene adducts. Our results suggest the formation of a biradical intermediate between the dienyl substrate and C(60). An electron transfer between the triplet excited state of C(60) and the dienyl substrate precedes the formation of the intermediate.
[反应：见正文] 二烯基环丙烷与C(60)的光环加成反应提供了一种新的合成方法，可立体定向地生成五元、七元和九元的[60]富勒烯加合物。我们的结果表明在二烯基底物与C(60)之间形成了双自由基中间体。在中间体形成之前，C(60)的三重激发态与二烯基底物之间发生了电子转移。
