addition products, depending on the nitrocompound and catalyst. The former product was favoured by the use of CuII in the catalytic system. Conversely, [60]fullerene underwent catalytic condensation, even in the absence of copper(II) salts, only with activatednitrocompounds and addition only with nitroalkanes in excess base. Note, the formal conjugated fullerene addition product was obtained in
AgNO<sub>2</sub>-mediated cleavage of the N–N bond of sulfonylhydrazones and oxygen transfer: access to fulleroisoxazolines via radical cyclization with [60]fullerene
The first example involving cleavage of the N–N bond of sulfonylhydrazones is presented, and a new methodology for the synthesis of fulleroisoxazolines is developed.

The addition of nitrile oxides to [60]fullerene is examined and it is
found that the reaction products regenerate [60]fullerene under relatively
mild conditions; the result is potentially useful for better control of
fullerene functionalization.
