실험 절차

To a solution of 89.9 g (7.9% w/w, 100%=7.1 g, 20.6 mmol) of 2,4,4-tribromobicyclo[3.2.1]oct-2-ene in chlorobenzene there are added 100 ml of acetonitrile and 100 ml of 10% sulfuric acid and stirring is carried out for 50 minutes at ambient temperature. The pH is then adjusted to 7 using aqueous sodium hydroxide solution and the aqueous phase is separated off. The organic phase is washed with 50 ml of water and then dried using magnesium sulfate. After filtration and removal of the acetonitrile using a rotary evaporator, 57.8 g (88% of theory) of 4-bromo-bicyclo[3.2.1]oct-3-en-2-one are obtained as a 6.3% solution in chlorobenzene.
