The kinetics of the thermal bromination of CF3I. Determination of the bond dissociation energy D(CF3−I)

Abstract: The kinetics of the thermal bromination reaction Brz + CFaI --+ IBr + CF& For the step have been studied in the range of 173-321°C.( 1 1) we obtainwhere 0 = 2.303RT cal/mole. that From the activation energy for reaction (1 11, we calculate D(CF3-I) = 52.6 + 1.1 kcal/mole at 25°C This is compared with previously published values of D(CF3-I). result to published work on k, for a combination of CF3 radicals is discussed.The relevance of the

“…The enthalpy of formation of n-C 3 F 7 and n-C 4 F 9 radicals is not experimentally available. There are, however, data concerning BDEs of the related n-alkyl iodides [19,32]. For these compounds, DH f has been evaluated by Joshi's method.…”

“…The table lists the initial translational energy E, the peak E'pk and average E'~v product translational energies and the reaction exoergicity AD 0. The reaction exoergicity was calculated u~ing the bond energy of OI from Radlein et al [12] and that of CF3I from Okafo and Whittle [13]. E'av of the product translational energy are roughly equal to the initial translational energies E but the peak translational energies E'pk occur at much lower values.…”
