    Reactions of Perfluoroethyl Radicals with Propane and Neopentane
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (4), 1972) Whytock, D A
    The reactions of C2F5 radicals with neopentane and propane have been studied, using perfluoroethyl iodide as the free radical source. The Arrhenius parameters, based on A= 1013.36 cm3 mol–1 s–1 and E= 0 for the combination of C2F5 radicals, are: [graphic omitted] Analysis of the propyl iodides in the products allows calculation of the Arrhenius parameters for C2F5 attack at specific sites in the propane molecule, providing the values: [graphic omitted] Arrhenius parameters for hydrogen abstraction from alkanes by C2F5, CF3 and C2H5 radicals are compared; C2H5 is the least reactive whilst CF3 and C2F5 have similar reactivities.
