Thermolysis of several sulfonyl azides in the presence Of C-60 leads either to aza[60]fulleroids or to mixtures of aza[60]fulleroids and corresponding aziridino-fullerenes, depending on the substituent at the sulfonyl group. In all cases, 1,2-closed aziridino-fullerenes can be obtained from azafulleroids by irradiation. Addition of sulfonyl azides to C-70 only yields azafulleroids with C-s-symmetry
在 C-60 存在下,几种磺酰叠氮化物的热解产生氮杂 [60] 富勒烯或氮杂 [60] 富勒烯和相应氮丙啶基-富勒烯的混合物,这取决于磺酰基上的取代基。在所有情况下,1,2-封闭氮丙啶-富勒烯都可以通过辐照从氮杂富勒烯中获得。将磺酰叠氮化物添加到 C-70 中仅产生具有 Cs 对称性的氮杂富勒烯。循环伏安测量表明,与 C-60 和 C-70 相比,电化学性能没有显着变化。((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)。
