반응 단계
Tetrabromonaphthalene-1,2-dicarboxylic anhydride: 2.0 g of naphthalene-1,2-dicarboxylic anhydride, 0.05 g of ferrum reductum and 5.2 ml of bromine are heated at 210° C. for 6 hours using a long intensive condenser. Working up analogously to Example 61a) gives 5.0 g of tetrabromonaphthalene-1,2-dicarboxylic acid, which is converted into the anhydride with acetic anhydride. Yield: 4.8 g (94%), bromine content: 62.4% (theoretical 62.7%).
