Mass spectrometry of alkylbenzenes and related compounds. Part II. Gas phase ion chemistry of protonated alkylbenzenes (alkylbenzenium ions)
Mass spectrometry and ion chemistry of alkylbenzenes, today, is much more than the gas-phase reactions of their radical cations and their prominent fragment ions, such as C7H7+ and C7Hs+'. Indeed, the gas-phase chemistry of gaseous ions originating mainly from the electron impact (EI) ionization of alkylbenzenes has been investigated extensively for more than 35 years and has revealed to us num...
متن کاملComparison study of the gas-phase oxidation of alkylbenzenes and alkylcyclohexanes
The goal of this paper is to present new experimental results obtained during the study of the gas phase oxidation of ethyl-benzene, n-hexyl-benzene, ethyl-cyclohexane and n-butyl-cyclohexane which belongs to two molecule families present in diesel fuels: alkylbenzenes and alkylcyclohexanes. Experiments were carried out in a jet-stirred reactor over the temperature range 550–1100 K. The new res...
متن کاملDehydrogenation of methanol by vanadium oxide and hydroxide cluster cations in the gas phase.
Bare vanadium oxide and hydroxide cluster cations, V(m)O(n)+ and V(m)O(n-1) (OH)+ (m = 1-4, n = 1-10), generated by electrospray ionization, were investigated with respect to their reactivity toward methanol using mass spectrometric techniques. Several reaction channels were observed, such as abstraction of a hydrogen atom, a methyl radical, or a hydroxymethyl radical, elimination of methane, a...
متن کاملMass spectrometry of alkylbenzenes and related compounds. Part I. Gas-phase ion chemistry of alkylbenzene radical cations
From the vantage point of an organic chemist, many previously obscure fragmentation and isomerization processes of gaseous organic ions have become chemically reasonable reaction pathways. The term scrambling, used formerly as a synonym for mechanistic dilemmas concerning crazy atoms, has almost vanished from mass spectrometry literature in recent years, mostly because of the recognition of wel...
متن کاملFungal Metabolism of n-Alkylbenzenes.
Isolates of Paecilomyces, Verticillium, Beauveria, and Penicillium species were tested for ability to metabolize a variety of n-alkylbenzenes. Minimum side chain lengths were required for metabolism of these substrates. These were C(4) for the Paecilomyces sp., C(8) for the Verticillium sp., and C(9) for the other two isolates. Growth on dodecylbenzene yielded benzoic and phenylacetic acids as ...
