Triacetoxyperiodinane → 4-Fluoro-3-nitrobenzaldehyde

참여 물질

반응 단계

To a stirred solution of (4-fluoro-3-nitro-phenyl)-methanol (750 g, 4.4 mmol) in DCM (40 mL) at 0° C. was added Dess-Martin Reagent (3.0 g, 7 mmol). The solution was stirred at room temperature for 4 hours. TLC showed disappearance of starting material. The reaction was quenched with 10% NaHCO3 and 10% Na2S2O3 aqueous solution and DCM layer separated and washed with water (100 mL) and brine (50 mL). The reaction was concentrated, and the residue was purified by flash chromatography on silica to obtain the title compound (570 mg, yield: 75%). 1H-NMR (400 MHz, DMSO-d6) δ 10.09 (d, 1H), 8.36 (t, 1H), 8.06 (dd, 1H), 7.97 (m, 1H).
