Photochemical reaction of ozone and benzene: An infrared matrix isolation study

The photolysis of benzene/ozone mixtures in an argon matrix at 12 K with UV light of λ ≥ 280 nm leads to the following products: phenol, 2,4-cyclohexadienone, benzene oxide, and butadienylketene (hexa-1,3,5-trien-1-one). The identification of butadienylketene as a product is based on deuterium isotopic shifts and agreement with density functional vibrational frequency calculations. We find an average phenol/ butadienylketene branching ratio of 4.3 during the course of photolysis. This is the first report in the literature of the observation of a ketene product from the reaction of oxygen atoms with benzene.
Reaction of Ammonia with Accelerated Benzoyl Ions under Multiple-collision Conditions in a Triple Quadrupole Instrument

The reaction of benzoyl ion with ammonia in multiple-collision conditions in the second quadrupole assembly of a triple quadrupole mass spectrometer at (laboratory) ion kinetic energies from 0 to 20 eV produced the even-electron ions +, m>+ (m=0,1) and + (n=0,1,2,3) and the odd-electron ions p>+. (p=0,1).Thermochemical information could not be obtained under multiple-collision conditions: both exotermic and endotermic reactions were observed, with no translational-energy onset measurable for the endothermic pr/cesses, nor decrease in the yield of the exothermic processes at high energies.The behaviour of cluster-ions intensities as pressure varied was qualitatively as expected.There are pressure and energy regions where spectra change little; if this feature were to be general, it would point to some utility for these conditions in qualitative analysis.
Photodissociation Study of C6H6O+. Ions in an Ion Cyclotron Resonance Spectrometer

Tautomeric phenol and 1,3-cyclohexadien-5-one radical cations exist as distinct, stable species in the gas phase.This is established by a study of the photodissociation spectra of C6H6O+. ions generated from four sources.Specifically, the ionized phenol and the C6H6O+. from phenetole exist principally as the phenol structure.On the other hand, C6H6O+. generated from bicyclooct-2-ene-5,7-dione and 2-phenoxyethyl chloride exist as a mixture of keto and enol structures.
