Abstract
A method of preparing tetrabromobenzoate compounds from tetrabromophthalic anhydride by reacting tetrabromophthalic anhydride with alcohol in the presence of a decarboxylation catalyst. The reaction may be carried out in an excess of alcohol, or with a near stoichiometric amount of alcohol by performing the reaction in an inert solvent.
