The reaction of CF3 radicals with CH3CN has been studied over the temperature range 298–623 K, using the photolysis of perfluoroacetic anhydride as a radical source. At temperatures higher than 473 K, the photolysis and the thermal decomposition of CF3I have also been used to generate CF3. — Arrhenius parameters for the reaction
were measured relative to the CF3 recombination.
The average value of the results from both sources of radicals gave the following parameters
The high primary kinetic isotope effect and the non‐curved Arrhenius plot found confirm the absence of an addition reaction.
