실험 절차

A mixture of (2-(difluoromethyl)phenyl)methanol (100 mg, 0.632 mmol) and manganese oxide (275 mg, 3.16 mmol) in dichloromethane was stirred at room temperature for twelve hours and then at 45° C. for 1 h. The reaction was filtered through celite and concentrated, to give 2-(difluoromethyl)benzaldehyde as an oil (99 mg). 1H NMR (400 MHz, CDCl3) δ 10.2 (s, 1H), 7.94 (d, 1H), 7.81 (d, 1H), 7.70 (m, 2H), 6.93 (t, 1H).
