Abstract
Abstract The gas-phase ion-molecule reactions of CF3+ with nitrogen-containing benzene derivatives (C6H5Y : Y = NH2, NO2, and CN), pyridine, pyrrole, and acetonitrile have been studied at near-thermal energy using an ion-beam apparatus. The major product channels are charge transfer for aniline (71.7 ± 0.5%), O− abstraction for nitrobenzene (91.7 ± 0.5%), electrophilic addition leading to initial adduct ions for benzonitrile (97.5 ± 0.8%), acetonitrile (100%), and pyridine (94.8 ± 0.4%), and electrophilic addition followed by HF elimination for pyrrole (80.0 ± 1.4%). The reaction mechanism is discussed based on product ion distributions and theoretical calculations of the energies of reaction pathways.
