WebCumene metabolism proceeds primarily through side-chain oxida-tion, but ring oxidation also occurs in vivo. Metabolism of cumene re-sulting in side-chain oxidation of α-methylstyrene to α-methylstyrene oxide or ring oxidation to arene oxides could potentially cause DNA damage. Arene oxides can form phenols, and when the para isomers WebApr 12, 2024 · 8. You can justify the formation of Benzaldehyde from Toluene by oxidising with peroxide just by looking at the mechanism of the reaction and think of migratory aptitude of Phenyl group , hydride and methyl group.
