N2  - 2-Phenylethyl radicals (Ph-CH2-·CH2) were prepared by the decarboxylation reaction of 3-phenylpropanoic acid with sulfate radical ions (SO4-·) formed during the pulse radiolysis of aqueous solutions containing peroxydisulfate (S2O82-) ions. The ultraviolet absorption spectrum of the transient radicals consisted of a band centred at 309nm with an extinction coefficient of 5000 1, mol-1 cm-1. Attempts were made to form phenylethyl radicals by the electron-attachment dissociation reaction of (2-haloethy1)benzenes. Contrary to literature reports, it was found that the latter reaction does not occur in either cyclohexane, benzene or aqueous solutions of (2-chloroethyl)- and (2-bromoethyl)-benzenes.
