Abstract

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.
