실험 절차

Thianthrene (20 g) was refluxed in 300 ml of acetic acid, and 36 ml of dilute nitric acid was gradually added dropwise thereto. After allowing the reaction to proceed for 5 hours, the reaction solution obtained was poured in 1.2 liter of water to precipitate a crystal. The crystal was collected by filtration and then recrystallized from acetonitrile to obtain 12 g of thianthrene-S-oxide. 1H-NMR (400 MHz, CDCl3): δ 7.42 (t, 2H), 7.56 (t, 2H), 7.63 (d, 2H), 7.93 (d, 2H).
