The kinetics of the forward and reverse reactions in the gas-phase system have been studied.The slow steps for the forward and reverse reactions, respectively, are .The Arrhenius parameters obtained, for the range 421-534 deg C, are .The competitive brominations of mixtures of i-C3F7H+C2F5H and i-C3F7H+n-C3F7H have been studied over the ranges 249-430 and 220-402 deg C, respectively.Each system yielded Arrhenius parameters for reaction (2) which are in excellent agreement with those given above.The results lead to the following bond dissociation energies at 298 K: Attempts were made to measure D<(CF3)3C-H> using competitive photobromination and photochlorination.However, (CF3)3C-H is so unreactive that only the approximate result D<(CF3)3C-H> ca. 456 kJ mol^-1 was obtained.The trends in C-H and C-Br bond dissociation energies are compared in alkanes, fluoroalkanes and the corresponding bromides.
