Some hydrogen abstraction reactions of the CF3CCl2 radical

Abstract
The gas phase photolysis of CF3CCl3 in the presence of several alkanes has been used to obtain Arrhenius parameters for the abstraction of hydrogen atoms by the CF3CCl2 radical: Activation energies of 9.6 and 8.0 kcal/mole are found for abstraction from secondary and tertiary C–H bonds, respectively. The Arrhenius parameters are compared to those for CCl3 and CF3 radicals.
