The gas phase photolysis of CF 3 CCl 3 in the presence of several alkanes has been used to obtain Arrhenius parameters for the abstraction of hydrogen atoms by the CF 3 CCl 2 radical:\documentclass{article}\pagestyle{empty}\begin{document}$${\rm CF}_{\rm 3} {\rm CCl}_2 + {\rm RH} \to {\rm CF}_{\rm 3} {\rm CCl}_2 {\rm H} + {\rm R}$$\end{document} 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 CCl 3 and CF 3 radicals.
