Disproportionation reactions between CF2H and C2H5 radicals in the gas phase

The disproportionation and combination reactions between CF₂H and C₂H₅ radicals have been studied in the gas phase from room temperature to 70°C. For the pathway which yields CF₂H₂ + C₂H₄, relative to CF₂HC₂H₅, Δ = 0.072 ± 0.019. The competing reaction channel that produces CF₂ + C₂H₆ is approximately four times as efficient, with Δ = 0.265 ± 0.038. With CF₂D radicals an isotope effect for the CF₂ + C₂H₅D reaction pathway was observed with Δ ? 0.2.
