Abstract: Gas phase ion molecule reactions of buckminsterfullerene (C60) with the ion systems generated from the self chemical ionization of alkyl methyl ethers(CH3OCnH2n+1, n=2, 3, 4) were studied in the ion source of a mass spectrometer. The adduct cation [C60C2H5O]+and protonated molecular ion [C60H]+ were observed as the major products. The former was produced by the reactions of C60with the methoxymethyl ion [CH3O=CH2]+, the latter corresponded to the proton transfer reactions from the protonated alkyl methyl ethers to C60. It is suggested that the [3+2] cycloadduct is the most favorable structure among the probable isomers with special chemical properties. Our investigation provides the guidance for the synthesis of this compound in condensed phase.
