Kinetic ESR for self reactions of perfluoroalkyl ether peroxyradicals

The rate constants for self-reactions of perfluoroalkyl ether peroxy radicals are found to be several order of magnitude greater as compared to the rate constants for their not fluorinated analogues. This difference of reactivity is interpreted in terms of fluorine substituents effects. Decay rate constants determined by kinetic ESR. Strong fluorine substituents effects observed.
