Here the reactivity of scandium oxide cluster anions toward n-butane was studied by using a high-resolution time-of-flight mass spectrometer coupled with a fast flow reactor. Hydrogen atom abstraction (HAA) from n-butane by (Sc2O3)NO (N=118) clusters was observed. The reactivity of (Sc2...
The rate constant of the direct reaction with peroxynitrite was (4.8 ± 1.4) × 10 3 M 1 s 1 (pH 7.4, 37°C). At low hydrogen sulfide concentrations, oxidation by peroxynitrite led to oxygen consumption, consistent with a one-electron oxidation that initiated a radical chain...
The synthesis and properties, with respect to oxygen transfer to olefins, of four peroxo Ti(IV) complexes of pyrazine- and pyridinedicarboxylic acids, are reported. The X-ray structure of Ti- [pz(COO)(COOH)](acac)(HMPA), 1, was performed; it essentially revealed that the pyrazine ligands ...
Synthesis and X-Ray Crystal Structure of Four μ2-Phenoxy Oxygen Bridged Macrocyclic Binuclear Cadmium(II) Complexes with Pendant Arms Four binuclear cadmium(II) macrocyclic complexes have been synthesized by [2+2] Schiff base condensation of tris(3-aminopropyl)amine (trpn) with sodium 2,6... ...
Reactivity of Radicals toward Oxygen, Hydrogen Donors, Monomers, and Additives: Understanding and Discussion Summary This chapter contains sections titled: Alkyl and Related Carbon-Centered Radicals Aryl Radicals Benzoyl Radicals Acrylate and Methacrylate R...

To understand the experimental data, DFT calculations were performed. They confirm a low oxidation barrier (0.11 eV) and show that oxygen is preferentially inserted at the periphery of the coronene and propose a reaction mechanism for fragmentation also involving a hydrogen atom. An estimate of the...
Oxidation of polyunsaturated fatty acids and lipids through thiyl and sulfonyl radicals: Reaction kinetics, and influence of oxygen and structure of thiyl ... Thiyl free radicals have been shown to react with polyunsaturated fatty acids via ion of bisallylic hydrogen, forming pentadienyl radicals, an...
The transfer of oxygen from water to oxygen in the uv photolysis of O3–H2O mixtures is studied as a function of the ozone and water vapor pressures using18O‐labeled H2O. It is shown that deactivation of the active species is generally competitive with the ordinary chemical reactions these sp...
The reaction of Ru3(CO)12 with 3-2dimethybut-1-yne (t-Butylacetylene) gives the mono-hydride HRu3(CO)9C2But in good yields. This complex reacts in hydrocarbon solvents with molecular hydrogen, to give the tri-hydride H3Ru3(CO)9C·CH2·CMe3 which, upon further hydrogenation, affords H4...
