Chemistry of Azafullerenes

3-dicarbonyl compounds are allowed to react with 2 the terminal attack is preferred if possible [22]. This is due to the thermodynamic stability of the corresponding cationic intermediates. a, 3-Unsaturated carbonyl compounds also 

Aza[60]fulleronium ion 28 has been isolated and characterized by X-ray crystallography via the oxidation of 2 with the radical cation hexabromo(phenyl)carbazole (HBPC ) in dry ODCB [27]. The counter-ion is the silver(I) complex carborane ion Ag(CBjjHgCl5)2]. The salt was crystallized as dark green crystals by diffusion of hexane vapor. The solid is reasonably air stable. has almost the same structure
