A reactant used in the preparation of selective inhibitors. In unsymmetrical Ullman reaction between methyl 5bromovanillate (II) and methyl 3-bromo-4-hydroxybenzoate (III) yielded all the three possible dicarbomethoxy-dibenzo-pdioxms which were separated by repeated chromatography over silica gel. A phosphorus- and bromine-containing bifunctional monomer has been prepared from bis(chloromethyl)methylphosphine oxide and the sodium salt of methyl 3-bromo-4-hydroxybenzoate.
