Gas-phase halo alkylation of C60-fullerene by ion-molecule reaction under chemical ionization.
Chemical ionization (CI) mass spectra of C60-fullerene were studied using 1,2-dibromoethane and 1,2-dichloroethane as CI reagents. The ion-molecule reaction between C60 and C2H4X(+) (X=Br and Cl) leads to the formation of (C60+C2H4X)(+) adducts. The collision-induced dissociation of the adducts reveal gas phase halo alkylation of C60-fullerence involving the C-C bond formation.
