β¦ Synopsis
Based on analysis of ESR spectra, it is suggested that the initial species formed by electron loss from oxirane( '%) in CFCIs at 77 K is the ring-closed o(n) radical, rather than the ring-opened "allylic" radical.

The irradiated halocarbon solutions of ethylene have been mvestlgated by ESR at low temperatures. I-butene catlon was found to be formed immediately after irradiation at 77 K. Upon warming. the cation was changed Into a new species, which was assigned to the propagating radxal. Possible mechanisms f
Reversible behavior for both electron transfers for oxidation of aromatic compounds to cation radicals and dications was observed in several common electrolytic solvents. Nitriles, nitro compounds and dichloromethane can all be rendered essentially nucleophile free for voltammetric purposes simply b
