実験手順
A solution of 4.20 g. of 1,1-diphenyl-2-propanone in 25 ml. of acetic acid is heated at 60°-70° C. and 1.0 ml. of bromine in 8 ml. of acetic acid is added dropwise. The reaction mixture is held at 60°-70° C. for one hour and then poured into ice. Toluene is added. The toluene layer is separated, washed with water, dried over magnesium sulfate and concentrated to obtain 1-bromo-3,3-diphenyl-2-propanone.
