Products of the radical reactions arising from t ‐Bu 2 O 2 , CF 3 I, and CH 3 I at 146°C in the vapor phase have been measured over a 33‐fold range of CH 3 I/CH 3 I ratios and shown to be governed by the rapidly established equilibrium\documentclass{article}\pagestyle{empty}\begin{document}$${\rm Me} \cdot + {\rm CF}_{\rm 3} {\rm I}\mathop {{\rm \rightleftharpoons}}\limits^K {\rm MeI} + {\rm CF}_{\rm 3} \cdot$$\end{document} Together with K estimated by thermochemical methods, the results yield, for the rate of recombination for CF 3 · radicals, k r = 10 9.7 ± 0.5 M −1 sec −1 .
