Thermal Decomposition of Some Perfluoro- and Polyfluorodiacyl Peroxides

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 deg C, all these peroxides undergo first-order decomposition in dilute 1,1,2-trichloro-1,2,2-trifluoroethane (Freon-113) solutions (F-RF.Differing from other perfluoro or polyfluoro radicals, the perfluoro-α-isopropoxyethyl radicals (10) undergo substantial β scission to form perfluoroisopropyl radicals (11) during their lifetime.The ΔHexc. values for the perfluoroacyl peroxides are about 24 kcal mol-1, or about 5 kcal lower than that of the nonfluorinated diacyl peroxides (ca. 29 kcal mol-1).Apparently, the higher relative rates for 3 and 7 are caused by different factors.The latter peroxide (7) decomposes with a more favorable ΔSexc. term, whereas the former (3) decomposes with lower values of both ΔHexc. and ΔSexc..Thus, weakening of the peroxide bond by H bonding of the peroxide oxygen atom with the acidic ω-hydrogen atom seems to be implicated in the decomposition of 3.With a half-life of 81 min at 20 deg C, 3 may become a useful low-temperature initiator for free-radical reactions and polymerization.
