| Abstract |
The gas-phase ion-molecule reactions of CH5+, C2H5+, and C3H5+ with five monosubstituted benzenes (M = PhX: X = H, CH3, C2H5, C2H3, and C2H） have been investigated 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 such adduct ions as (M + C2H5)+, (M + C3H5)+, and (M + C3H5 – C2H4)+. It was found that radiative association also participates in the formation of (M + C3H5)+ adduct ion for M = PhC2H. 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 mechanisms were discussed based on initial product-ion distributions and heats of reactions of each product channel estimated from semi-empirical quantum calculations.show more
