The kinetics of the reactions of CH₂CCl and C₂Cl₃ radicals with O₂ have been studied in a tubular flow reactor coupled to a photoionization mass spectrometer in the temperature range 298-648 K. Radicals were produced by the homogeneous photolysis of a suitable precursor using an excimer laser. The observed or indicated reaction mechanisms as well as the rate constants, which were measured as a function of density and temperature, suggest that both of these reactions proceed via the formation of a short-lived bound RO₂ intermediate that can either decompose back to the original reactants or form new oxygen-containing products following internal rearrangement of the adduct.
