实验步骤: A 30-ml four-necked flask was equipped with a stirrer, a thermometer and a reflux condenser. 0.011 g (0.05 mmol) of palladium (II) acetate, 1.442 g (15 mmol) of sodium-tert-butoxide and 10 ml of tetrahydrofuran were weighed in the flask, followed by stirring. Further, 0.029 g (0.05 mmol) of tri-tert-butylphosphonium tetra-para-tolylborate obtained in Example B-3 was weighed in air and added into the flask. The flask was purged with argon, followed by stirring at 25° C. for 30 minutes. 1.570 g (10 mmol) of bromobenzene was added, followed by stirring at 25° C. for 30 minutes. 1.476 g (11 mmol) of propiophenone was added, followed by stirring at 25° C. for 17 hours. After the completion of the reaction, 5 ml of water was added, followed by separation. The organic phase was purified by column chromatography to afford 2.061 g of 1,2-diphenyl-1-propanone (yield: 98 mol % based on bromobenzene). The identification of the product was made by mass spectroscopy, 1H-NMR and 13C-NMR. A 30-ml four-necked flask was equipped with a stirrer added into the flask The flask was purged with argon by stirring at 25° C. for 30 minutes by stirring at 25° C. for 30 minutes by stirring at 25° C. for 17 hours was added followed by separation The organic phase was purified by column chromatography

实验步骤: A 30-ml four-necked flask was equipped with a stirrer, a thermometer and a reflux condenser. 0.022 g (0.1 mmol) of palladium (II) acetate, 0.721 g (7.5 mmol) of sodium-tert-butoxide and 5 ml of tetrahydrofuran were weighed in the flask, followed by stirring. Further, 0.058 g (0.1 mmol) of tri-tert-butylphosphonium tetra-para-tolylborate obtained in Example B-3 was weighed in air and added into the flask. The flask was purged with argon, followed by stirring at 22° C. for 30 minutes. 0.563 g (5 mmol) of chlorobenzene was added, followed by stirring at 22° C. for 30 minutes. 0.738 g (5.5 mmol) of propiophenone was added, followed by stirring at 70° C. for 6 hours. After the completion of the reaction, 2.5 ml of water was added, followed by separation. The organic phase was purified by column chromatography to afford 0.810 g of 1,2-diphenyl-1-propanone (yield: 77 mol % based on chlorobenzene). The identification of the product was made by mass spectroscopy, 1H-NMR and 13C-NMR.
