I want to separate my target compound, 1, 3-phenylene bis[4-{[4-(pent-4-en-1-yloxy)phenyl]diazenyl}benzoate (ester) from the reactant 4-{[4-(pent-4-ene-1-yloxy) phenyl] diazenyl} benzoic acid. What about activated benzene ring with KMnO4 and heat? This repeats several times; the overall mechanism can go through several different pathways, but this is the essentials of it. Or does it just stay as ethane or what? Yes, the other product would cleave as a carboxylic acid to give H3C-COOH although it’s quite possible that under these reaction conditions the alpha-position of the carboxylic acid would undergo further oxidation to HOOC-COOH, (oxalic acid) which would then probably oxidize to CO2. © 2008-2020 ResearchGate GmbH. In that case, the double bond of cyclohexene will be attacked. Where can you draw these chemical equations? There is still a useful picture that explains the chemistry of this reaction quite well. and then add a carboxylic acid afterwards?
Hi James, what if side chain have one double bond in example 2. Hi James if the benzene ring has a carbon which has 3 OH groups attached to it will it get oxidised to benzoic acid? It is reduced. questions on the reactions between alkenes and potassium manganate(VII).
Can you please tell me if KMnO4 will react with one of these, if not which one and the name please?

Since this substitute has alpha carbon but also this is a ketone group.
I had to look up the structure of cardanol. I had a question. Here, KMnO 4 loses bonds to oxygen and becomes MnO 2.
Ph.D. Thesis, The University of British Columbia, November 1972. Anything with an OH directly attached to the ring will be oxidized to a quinone and from there it will produce a polymerized mess. So we need to work through all the possible combinations.
Thank you for this helpful page!
Protocol for the conversion of alkyl benzene to benzoic acid ?
How do we add COOH group while replacing benzylic hydrogen of say toluene?
Looking at the equation purely from the point of view of the organic reaction: The full equations are given below, although you probably won't need them. We'll look at the reaction with ethene. Given enough heating I would not be surprised to see oxidation. Carbonyl compounds are the predominant products in the oxidation of secondary C-H bonds. The rate constant for the oxidation of toluene by [BF3 center dot MnO4](-) is over 7 orders of magnitude faster than by MnO4- alone. I believe also in this particular case, the enol double bond can be broken by KMnO4 as alkenes do, forming the same product. Or it doesn’t really matter? Sure, but that will probably eventually oxidize to CO2 unless you’re careful. The situation with acidified potassium manganate(VII) solution is even worse because it has a tendency to break carbon-carbon bonds. The oxidation of alkanes and arylalkanes by KMnO4 in CH3CN is greatly accelerated by the presence of just a few equivalents of BF3, the reaction occurring readily at room temperature.
