실험 절차
To a stirred suspension of 100.0 g (0.504 mole) phenylsulfonylacetone in 500 ml carbon tetrachloride, 80 g [25.7 ml (0.5 mole)] bromine dissolved in 75 g carbon tetrachloride were added dropwise. The reaction mixture was stirred at ambient temperature overnight. The reaction mixture was filtered, and the precipitate was washed with hexane to give 139.8 g of the above-identified product.
