nonconjugated 4,4′-methylenediphenyl linkers was developed. The reaction of azomethine ylides derived from the bisaziridines with fullerene C60 was optimized and used for the stereoselective preparation of both the monoadducts (C60–linker–aziridine dicarboxylate), and the dumbbell bisadducts (C60–linker–C60). The reasons for the observed selectivity of the azomethine ylide formation and cycloaddition
