Nucleophilic Displacement of Bis(perfluoroalkanoyl) Peroxides with Perfluoroalkanoate

Abstract
Bis(perfluoroalkanoyl) peroxide ((RFCO2)2) suffered a nucleophilic displacement with perfluoroalkanoate (RF′CO2) to give new mixed peroxide (RF(CO)OO(CO)RF′). When thiophene was reacted with bis(perfluoroalkanoyl) peroxide in the presence of pyridinium perfluoroalkanoate, not only the perfluoroalkyl group (RF) of the peroxide, but also perfluoroalkyl group (RF′) of perfluoroalkanoate, was introduced into thiophene.
