Abstract:
Crossing the bridge : Two isomeric iminofullerenes, 5,6]‐open azafulleroid 1 and 6,6]‐closed aziridinofullerene 2 , were prepared by cycloaddition of an organic azide to C60. These “azalogues” enable the study of the effects of the bridging atom in a fullerene cage, that is, C60‐like (5,6‐open) versus PCBM‐like (6,6‐closed), as a function of their π systems (PCBM=6,6]‐phenyl‐C61‐butyric acid methyl ester).
