Synthesis of Benzopinacolone:[3]
To a clean test tube was added benzopinacol (100 mg, 2.7 x 10-4 mol), 100%
acetic acid (500 mL), followed by a single crystal of iodine. The mixture was heated over
a micro-burner until a solution was formed and then refluxed for five additional minutes.
After cooling to room temperature, the white precipitate, benzopinacolone, was collected
by vacuum filtration (Büchner funnel) and washed free of iodine using cold ethanol. The
white benzopinacolone crystals were air-dried and analyzed by FT-IR using a PE 1600
Series spectrometer.
