实验步骤: An oven-dried Schlenk flask was cooled to room temperature under an argon purge, and was charged with tetrakis(triphenylphosphine)palladium (289 mg, 0.25 mmol, 5 mol %) sodium carbonate (2.86 g, 27 mmol), and 1 (1.0 g, 5.0 mmol). The flask was purged with argon and DME (50 mL), ethanol (2 mL), water (15 mL), and 2-bromoiodobenzene (0.83 mL, 6.05 mmol) were added through a rubber septem. The mixture was heated to 85° C. with stirring for 3 days. The mixture was cooled to room temperature, diluted with ether (100 mL), and poured into a separatory funnel. The layers were separated and the organic phase was washed with 1M NaOH (2×50 mL), washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated in vacuo. The crude material was purified by flash chromatography on silica gel to afford 1.23 g (79%) of 2 as a colorless oil. purge were added through a rubber septem The mixture was heated to 85° C.

实验步骤: An oven dried Schlenk tube was evacuated and backfilled with argon and charged with tetrakis(triphenylphosphine)palladium (289 mg, 0.25 mmol, 5.0 mol %), 2-bromoiodobenzene (0.83 mL, 6.50 mmol), 4-(trifluoromethyl)phenylboronic acid (950 mg, 5.0 mmol), and sodium carbonate (2.86 g, 27.0 mmol). The tube was evacuated and backfilled with argon. To the tube was added (degassed) dimethoxyethane (45 mL), ethanol (2 mL), and water (15 mL) through a rubber septum. The reaction mixture was heated to 85° C. with stirring for 32 hours. The reaction mixture was then diluted with 2:1 hexane/ethyl acetate (100 mL) and poured into a separatory funnel. The mixture was washed with water (80 mL), and brine (80 mL). The organic layer was dried over anhydrous sodium sulfate, decanted, and concentrated in vacuo. The crude material was purified by flash chromatography on silica gel to afford 1.01 g (67%) of the product.
