With hydrogen bromide | 31 4-Bromo-2-butanone EXAMPLE 31 4-Bromo-2-butanone 70 Grams of methyl vinyl ketone is dissolved in 400 ml of ether and cooled to 0°. Anhydrous hydrogen bromide is bubbled in slowly until approximately 86 g is absorbed. The flask is stoppered and left at room temperature overnight. The solution is stripped of solvent and the residue distilled under reduced pressure to give the title product. | |
