Formation of C10H8+ from the Benzene Radical Cation: A Case for the Growth of Polycyclic Aromatic Hydrocarbon Ions by Ion/Molecule Reactions in the Gas Phase?
Abstract
Experimental results are reported which show that diacetylene, but acetylene, adds rapidly to C6H6 in the gas phase in helium at 0.35 Torr and 296 when C6H6 is produced by the chemical ionization of benzene with NO. The experiments were performed with the selected-ion flow tube (SIFT) and Fourier transform ion cyclotron resonance (FTICR) techniques. Chemical reactivity and ion photodissociation methods were employed to investigate the identity of the C10H8 produced by the addition reaction. Results were obtained for the reactions of this cation with deuterium, acetylene, diacetylene, styrene, trimethylamine, nitric oxide, 1,2,4,5-tetramethylbenzene and p-methylaniline, and were compared with the results of the reactions of these same molecules with the C10H8 radical cation produced directly from naphthalene by chemical ionization with Si and electron ionization.
