Abstract

Arrhenius parameters have been determined for the addition of trichloromethyl radicals to fluoroethylenes; for the unsymmfitric olefins the parameters have been determined for each end of the double bond. addition to CH₂ addition to CHF addition to CF₂ log A₂ E₂ log A₂ E₂ log A₂ E₂ CH₂ = CH₂ 5.6 3.2 CFH = CH₂ 5.4 5.4 CF₂ = CH ₂ 5.5 8.3 CH₂ = CHF 5.5 3.3 CF₂ = CHF 6.4 7.1 CH₂ = CF₂ 5.7 4.6 CFH = CF₂ 6.3 6.1 CF ₂ = CF₂ 7.1 6.1 (log A₂ in 1. mole^-1 sec^-1; E₂ in kcal mole^-1) The determined activation energies are compared with localization energies, and with free valence as calculated from simple Hückel theory.
