The 1,3-dipolar cycloaddition of nitrile oxides to C60 is described. These reactions result in the formation of fullerene-fused isoxazoline heterocycles bearing a series of different substituents in 3-position. The preparation and spectroscopic characterization of these compounds are reported, as well as some investigations of the reactivity of these heterocycles. It is found that fullerene isoxazolines are less reactive than aliphatic isoxazolines.
