The thermolysis of acyl acetyl peroxides containing alkyl substituents or a bromine atom at the /alpha/ position of the acyl group takes place with the simultaneous participation of homolytic and heterolytic processes. The contribution from the heterolytic processes increases linearly with decrease in the ionization potential of the corresponding free radical. During the thermolysis of diacyl peroxides in nonpolar solvents the possibility of heterolytic processes appears if the difference between the ionization potential of the radical corresponding to the electron-donating fragment and the electron affinity of the radical corresponding to the electron-withdrawing fragment is less than 480 kJ/mole.
