• The gas-phase ion-molecule reactions of CH5+, C2H5+, and C3H5+ with five monosubstituted benzenes (M) carrying a nitrogen atom in the substituent [PhX: X=NH2, NHCH3, N(CH3)2, NO2, CN] have been reinvestigated under a reactant-ion selective mode of an ion-trap type of GC/MS. The dependence of product-ion distributions on the reaction time indicated that collisional stabilization takes part in the formation of all adduct (M+C2H5)+ and (M+C3H5)+ ions. It was found that radiative association also participates in the formation of adduct (PhNH2+C3H5)+ and (PhCN+C3H5)+ ions. The initial product-ion distributions were determined by extrapolating the dependence of branching ratios of product ions on the reaction time to zero reaction time. The reaction mechanism was discussed based on initial product-ion distributions and heats of formation of each reaction pathway.
