The Claisen rearrangement converts allyl phenyl ether to o-allylphenol simply by heating to 200 C wi — Aromatic Hydrocarbons Chemistry Question

💡 Solution & Explanation

The reaction is purely thermal and requires no catalyst. The allyl group migrates to the ortho position via a highly ordered, six-membered cyclic transition state, initially forming a dienone which rapidly tautomerizes.
