Rate constants for radical recombination. III. The trifluoromethyl radical

Products of the radical reactions arising from t‐Bu2O2, CF3I, and CH3I at 146°C in the vapor phase have been measured over a 33‐fold range of CH3I/CH3I ratios and shown to be governed by the rapidly established equilibrium Together with K estimated by thermochemical methods, the results yield, for the rate of recombination for CF3· radicals, kr = 109.7 ± 0.5 M−1 sec−1.
