Electron spin resonance. Part 67. Oxidation of aliphatic sulphides and sulphoxides by the sulphate radical anion (SO4–˙) and of aliphatic radicals by the peroxydisulphate anion (S2O82–)
Autor: Richard O. C. Norman, Michael J. Davies, Bruce C. Gilbert
Publikováno v: J. Chem. Soc., Perkin Trans. 2. :503-509
E.s.r. experiments employing in situ photolytic decomposition of the peroxydisulphate anion (S2O82–) have been carried out to study the reaction of SO4–˙ with aliphatic sulphides and sulphoxides. For the former, ‘dimer’ radical cations (R2SS

Reactions of palladium(II) with organic compounds. Part 5. Effect of reaction conditions upon products of oxidation of α-methylstyrene
Autor: Grenville Watson, Richard O. C. Norman, C. Barry Thomas
Publikováno v: J. Chem. Soc., Perkin Trans. 2. :1099-1104
The effects upon product distribution of varying the temperature, time of reaction, and reagent concentrations have been investigated in the oxidation of α-methylstyrene by palladium (II) acetate. Two reaction pathways have been identified. A π-all

Electron spin resonance studies. Part 62. Acid-catalysed interconversion of β-hydroxyalkyl radicals: radical-cation intermediates
Autor: Bruce C. Gilbert, Peter S. Williams, Richard O. C. Norman
Publikováno v: J. Chem. Soc., Perkin Trans. 2. :1401-1405
Evidence is presented that isomerism of β-hydroxyalkyl radicals (e.g., the conversion of ·CH2CMe2OH into ·CMe2CH2OH) can be brought about in acid solution and that reaction occurs via the formation and hydration of a radical-cation. The reaction r

Electron spin resonance studies. Part XLVI. Oxidation of thiols and disulphides in aqueous solution: formation of RS˙, RSO˙, RSO2˙, RSSR–̣, and carbon radicals
Autor: Bruce C. Gilbert, Richard O. C. Norman, Roger C. Sealy, Hugh A. H. Laue
Publikováno v: J. Chem. Soc., Perkin Trans. 2. :892-900
Radicals which mediate in the oxidation of thiols with the TiIII–H2O2 couple and CeIV and of disulphides with the former reagent, in aqueous solution at room temperature, have been studied by e.s.r. spectroscopy. The e.s.r. evidence establishes tha

Autor: Richard O. C. Norman, Robin L. Willson, P.D.R. Marshall, Bruce C. Gilbert
Publikováno v: International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine. 26:427-434
SummaryThe rates of reaction of ‘metronidazole’ [1-(2-hydroxyethyl)-2-methyl-5-nitroimidazole] with e−aq, ·OH, ·CO−2, ·CH2OH, ·CHMeOH and ·CMe2OH have been measured by pulse radiolysis.E.s.r. data also show that metronidazole reacts rapi

Radical reactions in aqueous solution: use of the aci-anion of nitromethane as a spin trap
Autor: Richard O. C. Norman, Bruce C. Gilbert
Publikováno v: Canadian Journal of Chemistry. 60:1379-1391
The type of radical detected by esr when first-formed short-lived radicals are generated by photolytic, radiolytic, or flow techniques in the presence of nitromethane is shown to depend upon the nature and structure of the transient radical and on th

Publikováno v: J. Chem. Soc. B. :1004-1008
The following carbonyl compounds undergo one-electron reduction by the radicals ·CO2H, ·CO2–, or ·CMe2·NH2 to give species which have been characterised by their e.s.r. spectra; acetaldehyde, propionaldehyde, acetone, glyoxal, biacetyl, pyruval

Publikováno v: J. Chem. Soc., Perkin Trans. 2. :2174-2180
Reduction of carbonyl-conjugated radicals by TiIII and FeII in aqueous solution has been investigated by e.s.r. spectroscopy and pulse radiolysis. Kinetic data have enabled the importance of such reactions in metal ion–hydrogen peroxide systems to
