実験手順

Cyclohexane-1,3-dione (11.2 g, 0.1 mol) was suspended in ice water (70 mL) and bromine (5.16 mL, 0.1 mol) was added dropwise over 5 minutes. The resulting suspension was stirred at room temperature for 3 hours. The suspension was filtered and the solid was stirred in water (200 mL) for 30 minutes. The solid was collected by vacuum filtration, rinsed with water, and dried to render crude product. The crude product was recrystallized from ethanol to produce the title compound.
