Abstract
Various azoarenes undergo reductive fission with hydrazine hydrate in refluxing ethanol to give easily isolable aminoarene(s) using aluminium powder. The reaction is fast and cost effective: yields are excellent ranging from 85-95%; substituents like –OH, –OCH3, –COOH, –Cl, –Br are unaffected. The method affords a simple and convenient route to the preparation of substituted aminoarenes.
