# Oxidation of naphthalene with KMnO4

What is the product when naphthalene is oxidized by alkaline (or acidic) solutions of $\ce{KMnO4}$?

Some possible reactions show up in a google search, but they have no references:

1. Naphthalene to phthalic acid by alkaline $\ce{KMnO4}$:
2. Another product on oxidation of napthalene by alkaline $\ce{KMnO4}$:

If possible, please include the reaction mechanisms in the answer as well.

• Quick search on Reaxys shows that both the products you've already listed have been made, also plus 2-formylbenzoic acid. Some are from 19th-century Chem. Ber. articles, which I'm not inclined to look up. – orthocresol Jan 19 '18 at 21:45
• @orthocresol , Is there a reaction mechanism? If not, can you post this as answer? – Shoubhik R Maiti Jan 21 '18 at 10:00
