Free Radicals by Mass Spectrometry. VI. The Bond Dissociation Energies of Some Methyl, Allyl, and Benzyl Compounds by Electron Impact

Abstract
The appearance potentials for the radical ions from methyl, allyl, and benzyl halides and two other derivatives have been measured. Using previously measured values for the ionization potentials of the free radicals, the R–X bond dissociation energies in these compounds have been calculated. The results are in good agreement with published data for the methyl and allyl compounds, and in fair agreement for the benzyl halides.
