Can someone please guide me about the reaction protocol for alkyl benzene to benzoic acid using KMnO4 or any other oxidizing agent.
Thanks,
KMnO4 is a strong oxidizing agent. It oxidizes alkylaromatics to corresponding carboxylic acid (over oxidation product).
As long as there is one or 2 benzylic hydrogen(s), oxidation of an alkylbenzene into carboxylic acid is possible. For example, toluene or isopropylbenzene are oxidizable while tert.-butylbenzene is NOT.
This is the full procedure to do an oxidation of an alkylbenzene or a dialkylbenzene:

Wishing you success in your research.
You can convert alkyl benzene to benzoic acid by oxidation of alkyl benzene with alkaline KMnO4 . Heat the reaction mix. containing alkyl benzene, aq.Na2CO3 for 3 hrs., cool & neutralize with HCl. The ppt. of acid separates out.
Where is the interest to transform allyl benzene to benzoic acid??
Which one is more expensive??
There is a lost of Carbon!!
Benzadehyde in air for some hours will lead to benzoic acid
