Wallach rearrangement

What is Wallach rearrangement?

The Wallach rearrangement is a chemical reaction in which azoxybenzenes are rearranged under acidic conditions to produce p-hydroxyazobenzenes. This reaction is catalyzed by an acid and involves a rearrangement of the molecular structure. As a result of the Wallach rearrangement, the starting material, azoxybenzenes, are transformed into p-hydroxyazobenzenes.
