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. Cyclic‐voltammetric measurements revealed that there is no significant change of electrochemical properties compared to C 60 and C 70 . (© Wiley‐VCH Verlag GmbH & Co.
