Method for preparing 3,5,3',5'-tetrabromo-2,4,2',4'-tetraoxydiphenyl

The method for preparing 3,5,3',5'-tetrabromo-2,4,2',4'-tetraoxydiphenyl consists in that 2,4,2',4'-tetramethoxydiphenyl is processed with an acid agent, such as aluminium chloride, aluminium bromide, or hydrogen bromide in acetic acid, in a medium of an organic solvent at a temperature up to 120°C; the obtained 2,4,2',4'-tetraoxydiphenyl is then processed with bromine in a medium of an organic solvent and the end product is finally isolated.
