Synthesis Route: The synthesis of benzanthrone typically starts with anthraquinone and glycerol, undergoing the following steps: Reduction: Anthraquinone is reduced with iron powder in the presence of copper sulfate to form hydroxyanthraquinone; Dehydration: Glycerol undergoes dehydration under concentrated sulfuric acid to produce acrolein; Condensation: Hydroxyanthraquinone reacts with acrolein in the presence of sulfuric acid to undergo a condensation reaction, losing one molecule of water to form a new ring; Oxidation: Finally, the intermediate is oxidized by sulfuric acid to yield benzanthrone. Other synthesis methods include C-H bond activation and cyclization reactions using palladium catalysts, or oxidation of benzophenanthrene derivatives, among other pathways.
