Procedimiento

40% Boron trifluoride-acetic acid complex, 5.5 g, was ice-cooled and a mixture of 2 g of 4-phenylcyclohexanone and 2.35 g of acetic anhydride was dropwise added to the complex. After stirring for 30 minutes under ice cooling and at room temperature for 4 hours, 10 ml of saturated ammonium acetate aqueous solution was added to the mixture followed by stirring at 80° C for 1.5 hours. The reaction mixture was extracted with ether and the extract was purified to obtain 1.77 g of 2-acetyl-4-phenylcyclohexanone.
