Περίληψη:	Bisazafullerene (C 59 N) 2 has been functionalized under aerobic conditions with cyclo-[2]-octylmalonate through a Mannich-type reaction, furnishing the corresponding monoadduct. A regioselective tether-directed Bingel cyclopropanation reaction was then carried out on the azafullerene core to yield a single bisadduct. Spectroscopic analysis of the formed bisadduct showed it to have a C 1 symmetrical structure, making it inherently chiral. Single-crystal X-ray analysis revealed the addition pattern of the azafullerene bisadduct to be equatorial face . Examination of the optical properties showed the evolution of new absorption bands, which can be used as signatures for the characterization of equatorial face bisadducts of C 59 N. Finally, redox assays showed that the LUMO level of the equatorial face bisadduct was increased compared to that of the parent (C 59 N) 2.
