The reactions of neopentyl radicals in an oxidising environment have been studied by adding neopentane to slowly reacting mixtures of H2 + O2 over the temperature range 380 - 520 deg C.Over a wide range of mixture composition, the only detectable initial products at these temperatures are 3,3-dimethyloxetan (DMO), acetone, i-butene, methane, and formaldehyde.A relative simple mechanism involving the formation of neopentylhydroperoxide (QOOH) radicals gives a quantitative interpretation of the product yields.Although the major source of i-butene is the C-C homolysis of neopentyl radicals, a significant proportion is formed in reaction (6) (CH3)2C(CH2OOH)CH2 <*> (CH3)2C=CH2 + HCHO + OH.From measurements of the product ratios (
