2,2-[60]Fullerenoalkanoyl chlorides (1a−d) were easily and securely prepared from the corresponding 2,2-[60]fullerenoalkanoic acids (2a−d) by the reaction with thionyl chloride in an unusual mixed solvent, CH2Cl2/dioxane. The characterization of 1a−d by 1H and 13C NMR, FT-IR, and MALDI-TOF-MASS was conducted for the first time. The 2,2-[60]fullerenoalkanoyl chlorides thus obtained were readily converted

2,2-[60]Fullerenoalkylamines were easily and securely preparedfrom 2,2-[60]fullerenoalkanoyl azides, which were simply obtained from the corresponding 2,2-[60]fullerenoalkanoyl chlorides through the Curtius rearrangement in the presence of tert-butyl alcohol, followed by debutylation and decarboxylation under acidic conditions.
