Gas phase studies of Zn+2, Ag+3, and Ag+5

Laser desorption from ZnO and AgO produces small bare metal cluster ions.Laser desorption from a ZnO/AgO mixture produces an enhancement of the silver cluster ion signal with complete suppression of the zinc signal.The chemistry of Zn2+ indicates IP(Zn2) = 9.0 +/- 0.2 eV and D0(Zn+ - Zn) = 0.56 +/- 0.2 eV.The reactivity of Zn2+ with alkenes and alcohols is characterized by displacement of a zinc atom and formation of Zn+ - B (B = alcohol, alkene).The silver cluster ions are produced with excess kinetic energy; however, collisional cooling is achieved by trapping the cluster ions in a static pressure of argon.Charge transfer reactions indicate IP ( Agn ) nL2+ (n = 3,5; L = sec-butylamine) reacts with sec-butylamine via deamination and dehydrogenation indicating D0g (AgnL2+ - butadiene) > 1.73 eV.

One-Electron Oxidation of Alkylbenzenes in Acetonitrile by Photochemically Produced NO3.: Evidence for an Inner-Sphere Mechanism

The reaction between NO3. and polyalkylbenzenes was studied using 308-nm laser flash photolysis of cerium(IV) ammonium nitrate in the presence of the alkylbenzenes in acetonitrile solution.For all benzenes, with the exception of monoalkylbenzenes and o- and m-xylene, the reaction with NO3. was found to yield the corresponding radical cations and to proceed in an apparently straightforward bimolecular manner.For monoalkylbenzenes and o- and m-xylene, radicals were seen which are derived from the parents by formal loss of H. from the side chain of the aromatic.This reaction proceeds via a complex between the aromatic and NO3. with the decomposition of the complex being rate determining at higher concentrations of aromatic (rate constants for decomposition between 6 * 105 and 4 * 107 s-1).In the complex, electron transfer from the aromatic to NO3. is suggested to be concerted with deprotonation of the incipient radical cation.Formation of a complex between NO3. and aromatics is likely even in those cases where radical cations are observed, with the assumption that in these cases the complex decomposition rate is greater than 6 * 107 s-1.

Benzene and Alkylbenzene Cations: An Electron Spin Resonance Study

Exposure of solutions of benzene, toluene and the xylenes in fluorotrichloromethane solvent at 77 K to 60Co γ-rays gave the corresponding radical cations, identified by e.s.r. spectroscopy.Trends in the methyl proton hyperfine coupling constants for these and for alkene cations are discussed in terms of electron-transfer from the C-H ?-orbitals.
