The synthesis of benzoyl peroxides with fluorine-containing substituents at various positions in the benzene ring was realized by the acylation of an alkali-metal peroxide by fluorine-substituted benzoyl chlorides and also by the reaction of the fluorine-substituted benzoic acids with hydrogen peroxide in the presence of N,N'-dicyclohexylcarbodiimide.A mechanism is proposed for the production of the peroxides by the carbodiimide method.The rate constants and activation energies were determined for the thermal decomposition of the synthesized peroxides in chlorobenzene.The rate constants for the decomposition of the substituted aromatic peroxides correlate with the Hammett ? constants on the fluorine-containing substituents.
