In each case the permanganate oxidises the most electron rich ring. In the nitro-substituted case, that is the unsubstituted ring, probably first at the position alpha to the nitro group, forming a phenol, then para to that to a quinone but permanganate keeps on chewing until the phthalic acid is formed. In the aniline case the most electron ...

WebOxidation of Alkyl Side-Chains. The benzylic hydrogens of alkyl substituents on a benzene ring are activated toward free radical attack, as noted earlier. Furthermore, SN1, SN2 and E1 reactions ofbenzylic halides, show enhanced reactivity, due to the adjacent aromatic ring. The possibility that these observations reflect a general benzylic ...

WebOct 10, 2024 · This is known as "side chain oxidation." When a compound which has an alkyl group directly attached to an aryl group is treated with a strong oxidizing agent like potassium permanganate (KMnO 4 ) or Jones Reagent (CrO 3 /H 2 SO 4 ), the benzylic carbon is oxidized to a carboxylic acid group which remains attached to the aryl group. WebAug 9, 2024 · To my knowledge, side chain oxidation with KMnO4 occurs only when a benzylic hydrogen is present. However this doesn't contain a benzylic hydrogen and hence according to me it wouldn't give any reaction. However the answer in my book states that Phenylacetylene will be oxidized to benzoic acid.
WebSep 8, 2024 · It will depend on the reaction conditions used. I think it would be possible to find conditions that give majority oxidative cleavage. @Waylander what kind of conditions would favor oxidative cleavage over side-chain oxidation? I thought the reactants and conditions are largely similar for the two? WebJan 5, 2024 · In rat studies, it was found that the metabolic oxidation of 2,6-diisopropylnaphthalene happens on the isopropyl side chain [9, 10]. 1-Methylnaphthalene, 2-methylnaphthalene, 1-ethylnaphthalene, 2-ethylnaphthalene, 2,7-dimethylnaphthalene were oxidized on the alkyl chain to alcohol metabolites in vitro by P450 CYP101B1 obtained …
