Oxidation of the nickel complexes [(BOXAM)Ni(R)] (HBOXAM = bis((4-isopropyl-4,5-dihydrooxazol-2-yl)phenyl)amine) with R = CF3, CH3, Cl leads to the corresponding radical cationic complexes, which rapidly undergo homolytic Ni-R bond s
Spin trapping of fluoroalkyl radicals
Gille, Lars,Stoesser, Reinhard
, p. 191 - 194 (1994)
The formation of fluoroalkyl radicals in liquid chlorofluorocarbons (CF2Cl-CFCl2, CFCl3, CFCl2-CH3, CHF2-CF2-CF2Cl, CF3-CFH-CF3 and CCl4) has been investigated by means of the spin trapping technique and ESR spectroscopy.It is shown that the primary fluoroalkyl radicals which were generated in these compounds by ionising radiation are preferably formed by bond cleavage at carbon atoms attached to one fluorine atom.Besides the liberation of chlorine atoms in chlorine-containing compounds, in CHF2-CF2-CF2Cl and CF3-CFH-CF3 fluorine atoms were also detected.By comparison of radicals formed from γ-irradiated CF2Cl-CFCl2 (CFC-113) and from CF2Cl-CFClI or CF2I-CFCl2 by zinc reduction, it was demonstrated that in CFC-113 both .CF2-CFCl2 and .CFCl-CF2Cl radicals are formed, whereas in iodine-containing homologues the formation of one species is favoured. - Keywords: Spin trapping; Fluoroalkyl radicals; ESR spectroscopy; γ-Irradiation; Zinc reduction; Phenyl-tert-butylnitrone

Azidyl, cyanatyl, and cyanyl radicals and chlorine atoms have been detected by spin trapping using α-phenyl-N-tert-butyl nitrone (PBN) in the monoelectronic electrooxidations of azide, cyanate, cyanide, and chlorine.Azidyl and cyanatyl radicals were also detected with PBN in the persulfate oxidations of azide and cyanate.Azidyl radicals could be detected in the reaction of azide with hydroxyl radicals in the presence of PBN.
