ABSTRACT:
Bromine is generated in situ in a mixture formed by mixing together 2-methoxynaphthalene, hydrogen bromide, at least one peroxidic compound and a chemically indifferent organic liquid solvent or diluent under conditions effective to produce 1,6-dibromo-2-methoxynaphthalene. Optionally, but preferably, water is also included in the mixture. Regioselective hydrodebromination of 1,6-dibromo-2-methoxynaphthalene with hydrogen and tungsten carbide enables production of 2-bromo-6-methoxynaphthalene.
