4-Fluoro-2-(trifluoromethyl)aniline

clear light yellow to pale brown liquid

General procedure: A 25 mL of Schlenk tube equipped with a magnetic stir bar were charged with aniline (1.2 mmol, 3.0 equiv) or heterocycles (0.8 mmol, 2.0 equiv), K2CO3 (0.8 mmol, 2.0 equiv) and fac-Ir(ppy)3 (2.6 mg, 0.004 mmol, 1 mol percent), under air. The vessel was evacuated and backfilled with Ar (3 times), CF3I stock solution (0.56 mL, 0.71 mmol/mL in 1, 2-chloroethane or 0.36 mL, 1.11 mmol/mL in DMSO, 1.0 equiv), anhydrous 1, 2-dichloroethane (3 mL) were then added. The tube was screw capped and stirred at room temperature under irradiation of blue LEDs (12 W) for 24 hours. The reaction mixture was filtered through a pad of Celite and washed with ethyl acetate (3×5 mL). The filtrate was concentrated. The residue was subjected to column chromatography on silica gel to afford the pure product.In the preparation method of the trifluoromethyl aromatic amine of the present embodiment, the aromatic amine is p-fluoroaniline, and other reactions and post-treatment processes are the same as in the embodiment 28.
