Benzoyl chloride, 2-chloro-5-nitro- → 2-Chloro-5-nitrophenyl 2-furyl ketone

참여 물질

반응 단계

To a mixture of 2-chloro-5-nitrobenzoyl chloride(5.50 g, 0.0250 mol) and tetrahydrofuran is added 2-tributylstannylfuran (10.1 g, 0.0275 mol) followed by dichloro-bis-triphenylphosphine palladium (0.540 g, 0.00075 mol). The resultant mixture is stirred overnight at room temperature and concentrated in vacuo. The resultant oil is chromatographed on silica gel with methylene chloride-hexanes to afford the title compound as a bright yellow solid (4.95 g, 78.7%, mp 93-96° C.) which is identified by IR and NMR spectral analysis.
