<p>The displacement of halogen from a 1,2,3-trihalo-4,6-dinitroresorcinol can be carried out in an aqueous medium using alkali metal hydroxide to form 2-halo-4,6-dinitroresorcinol. The product is a useful intermediate in the synthesis of 4,6-diaminoresorcinol, which is a monomer for polybenzoxazole polymers. The process forms part of a useful aqueous process for synthesizing 4,6-diaminoresorcinol.</p> |
