Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone. In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate: The cumene process is conducted on such a large scale that even the small amount of acetoph… WebQuinones can be prepared by the oxidation of phenols or anilines, although generally in poor yield. However, appropriately disubstituted phenols or anilines are easily oxidized to give better yields of quinones. 1,4-Quinones are more easily prepared and are substantially more stable than 1,2-quinones. Milder oxidizing agents are required to ... eporcha gov bd cheek
