Abstract:

Gas-phase ion-molecular reactions of C60 and C70 with the ion system of acetone have been studied in this paper. The ions of protoned and acetylized C60 and C70 were formed by the reactions of C60 and C70 with some ions which existed in the ion system when mass spectrometer worked on chemical ionization conditions. The reactivity of C70 is greater than that of C60. Results of quantum chemical calculation for the adduct ions showed a σ bond between the acyl carbon atom and C60 may be formed. These results will provide some valuable informations on the condense-phase acetylization of C60.
