✦ Synopsis

Gas

-phase ion-molecule reactions of buckminsterfullerene (C 60 ) with the ion systems generated from the self-chemical ionization of alkyl methyl ethers (CH 3 OR, R = n-C 2 H 5 , n-C 3 H 7 , n-C 4 H 9 ) were studied in the ion source of a mass spectrometer. The adduct cation [C 60 C 2 H 5 O] and protonated molecule [C 60 H] were observed as the major products. The former adduct ion was produced by the reactions of C 60 with the methoxymethyl ion [CH 3 OCH 2 ] , and the latter resulted from the proton transfer reactions from protonated alkyl methyl ethers to C 60 . It is suggested that the [32] cycloadduct to a 6-6 bond of C 60 (a C-C bond common to two annulated six-membered rings) is the most favorable structure among the probable isomers of [C 60 C 2 H 5 O] .

2-Methoxyethanol chemical ionization of amines, carboxylic acids and amino acids has been found to produce numerous adduct ions. The most intense adduct ions for amines are [M H] and [M 77] , for carboxylic acids [M 27] , [M 59] and [M 77] , and for amino acids [M H] , [M 13] , [M 27] and [M 77] . E

Ion-molecule reactions of four isomeric cyclopropane derivatives were investigated under chemical ionization(CI) conditions, using methane, acetone and vinyl acetate as reagent gases. The methane positiveion CI mass spectra of each of two isomer pairs 1,2 and 3,4 are identical, and so are the collis
