실험 절차
In 300 ml of acetic acid was refluxed 20 g of thianthrene and 36 ml of diluted nitric acid was gradually added dropwise thereto. After reacting for 5 hours, the reaction solution was poured into 1.2 liters of water to deposit crystals. The crystals were collected by filtration and recrystallized from acetonitrile to obtain 12 g of thianthrene-S-oxide. 1H-NMR (400 MHz, CDCl3): σ 7.42 (t, 2H), 7.56 (t, 2H), 7.63 (d, 2H), 7.93 (d, 2H).
