Seven polyfluoroacyl peroxides were synthesized, some of them by a new procedure involving the direct interaction of an acyl fluoride with hydrogen peroxide. In the temperature range of 20-40" C, all these peroxides undergo first-order decomposition in dilute 1, 1, 2- trichloro-1, 2, 2-trifluoroethane (Freon-113) solutions (50.02 M.). The major decomposition products were separated and characterized as the coupling products of the corresponding ...
