Effect of Alkyl and Halo Substituents on the Homolytic Dissociation of Dibenzyl Hyponitrites

Abstract

POLAR effects showing consistent trends with the nature of substituents and satisfactory correlations with the Hammett equations have been observed in the homolytic dissociations of benzoyl1 and thenoyl peroxides2, t-butyl perbenzoates3, phenylperacetates4 and peroxycarbamates5, and m-substituted phenylazotriphenylmethanes6. In all these reactions electron-repelling substituents have been found to increase reaction rate whereas electron-with-drawing substituents lower rates, the magnitude of the effects being much smaller than in ionic reactions.
