The reactions of methyl radicals with 3-methyloxetane, 3,3-dimethyloxetane and 2,2-dimethyloxetane have been studied.The overall rates of hydrogen-atom abstraction from these three compounds have been obtained over the temperature range 100-200 deg C by assuming the value of Quinn and coworkers (J.Chem.Soc.Faraday Trans.I, 1976, 72, 1935) for the rate of recombination of methyl radicals.The following rate expressions were found: log10(k4/cm3mol-1s-1)(30x) = 11.69 (+/-0.20)-38.23 (+/-0.84) kJmol-1/2.303RT, log10(k4/cm3mol-1s-1)(3,30x) = 11.72 (+/-0.20)-39.47 (+/-1.0) kJmol-1/2.303RT, log10(k4/cm3mol-1s-1)(2,20x) = 11.99 (+/-0.23)-41.24 (+/-1.13) kJmol-1/2.303RT.From these rate expressions and those obtained previously for three other oxetane molecules, the rate parameters for hydrogen-atom abstraction from five distinct sites in the substituted oxetane molecules have been obtained.
