ABSTRACT:
Dibrominated naphthol compounds, e.g., 1,6-dibromo-2-hydroxynaphthalene, are regioselectively catalytically hydromonodebrominated, e.g., into 6-bromo-2-hydroxynaphthalene, by reacting such dibromonaphthols with molecular hydrogen, or a precursor compound that generates nascent hydrogen in the medium of reaction, in an acidic organic solvent and in the presence of a catalytically effective amount of a tungsten carbide-based catalyst.
