3-bromophenylboronic acid (0.249g,2mmol), 5wt%Pd/CaCO3(0.0456g,Pd0.01mmol) and CuI(0.0114g,0.03mmol) are added to a 250mL polytetrafluoro-lined pressure reaction kettle, then DMSO(10mL) is added, the reaction kettle is installed, 1.85atm of air is slowly introduced into the fume hood, and then, the reaction kettle was then placed in an oil bath at 50°C for 12 hours. After stopping the reaction, cool the reaction kettle to room temperature and slowly release the remaining gas in the fume hood. Start the reaction kettle, add 40mL of ammonia water with a mass concentration of 5%, filter and separate the palladium catalyst, which can be reused after washing and drying. The mother liquor was extracted three times with dichloromethane (30mL), and the organic phase was combined. The organic phase was dried with anhydrous sodium sulfate, and the solvent was removed by vacuum concentration to obtain a crude product. The product was purified by column chromatography (volume ratio of 20:1 petroleum ether/ethyl acetate as eluent) to obtain bis (3-bromophenyl) ketone.
