The mechanism of the allylic oxidation of 2-methyl-2-butene with selenium dioxide has been investigated by ab initio quantum mechanics. Transition states for two major steps (an ene reaction and a [2,3]-sigmatropic rearrangement) of this reaction have been optimized by the B3LYP/6-311+G(d,p) method.
The relative OH reaction rates from the simulated atmospheric oxidation of 4-methyl-2pentanone, trans-4-octene, and trans-2-heptene have been measured. Reactions were carried out at 297 t 2 K in 100-liter FEP Teflon"-film bags. The OH radicals were produced from the photolysis of methyl nitrite. The
