Electron Spin Resonance Studies. Part 71. Side-chain Oxidation Pathways in the Reactions of .OH and SO4-. with Some Phenyl-substituted Carboxylic Acids, their Anions, and Some related Compounds

A series of arene radical-cations has been generated in situ by the reactions of methylbenzene, phenylethanoic acid, and some derivatives and cyclic analogues with both SO4-. and .OH (the latter in acid solution).The results are interpreted in terms of a variety of subsequent rapid reactions including hydration, deprotonation (to give benzylic radicals), and fragmentation (decarboxylation: for a series of radical-zwitterions +.Ar(CH2)nCO2- (n=1-3) decarboxylation (k >/= 1E9 dm3 mol-1 s-1) appears to proceed via direct intramolecular elecron-transfer, though in some cases formation of a discrete ?-bonded intermediate cannot be ruled out.

Ultraviolet Absorbtion Spectra of the 2-Phenylethyl Radical Formed During Pulse Radiolysis

2-phenylethyl radicals (Ph-CH2-CH2) (radical) were prepared by the decarboxylation reaction of 3-phenylpropanoic acid with sulfate radical ions (SO4- radical) formed during the pulse radiolysis of aqueous solution containing peroxydisulfate (S2O82-) ions.The ultraviolet absorbtion spectrum of the transient radicals consisted of a band centred at 309 nm with an extinction coefficient of 5000 l. mol-1 cm-1.Attempts were made to form phenylmethyl radicals by the electron-attachment dissociation reaction of (2-haloethyl)benzenes.Contrary to literaturereports, it was found that the latter reaction does not occur in either cyclohexane, benzene or aqueous solutions of (2-chloroethyl)- and (2-bromoethyl)-benzenes.

Studies on the Spirooctadienyl Radical and the 2-Phenylethyl Rearrangement

The title radical, 5, has been generated by hydrogen atom abstraction from spiroocta-4,6-diene (4).The radical could not be observed by EPR spectroscopy even at temperatures as low 100 K.Instead, the EPR spectrum of the cyclopropyl ring-opened produc
