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.
