General procedure: To a flame dried 100mL flask were added 1,3-disustituted benzene (3.0mmol), TMEDA (1.1equiv, 3.3mmol), DIPA (5%equiv, 0.16mmol), and THF (10.0mL). The solution was cooled to -78C for 10min and then n-BuLi (1.1equiv, 3.3mmol) was added dropwise. The mixture was kept at this temperature for 1h; DMF (1.5equiv, 4.5mmol) was added and the mixture was further stirred for another half an hour at -78C. The mixture was allowed to warm up to room temperature and quenched by the addition of saturated NH4Cl-H2O solution (5mL); extracted three times with ethyl acetate (10mL×3). The combined organic layers were dried over anhydrous MgSO4, filtered, and concentrated in vacuo. The regioselectivity of the crude product was ascertained by 19F NMR (for fluorinated products) or by GC/MS (for nonfluorinated ones) and then subjected to flash chromatography to obtain the desired products which were characterized by 1H NMR, 19F NMR, and 13C NMR spectral data and GC-MS analyses.
