Reaktionsschritte
A suspension of 6.71 g (55 mmol) of phenylboronic acid, 9.95 g (50 mmol) of 3-bromoacetophenone, 30 mg (0.13 mmol) of palladium acetate, 17.28 g (125 mmol) of potassium carbonate and 16.12 g (50 mmol) of tetrabutylammonium bromide in 55 ml of water was vigorously stirred under a stream of nitrogen and then stirred at 70° C. under an atmosphere of nitrogen for 75 minutes. Water was added to the reaction mixture and the mixture was extracted with tert-butyl methyl ether. Then, the organic layer was dried and concentrated. The residue (10.23 g) was subjected to silica gel column chromatography (eluted with n-hexane:ethyl acetate=7:1) to obtain 9.82 g of 3-acetylbiphenyl as oil.
