Hydrogen Bromide → 1-Propanone, 2-bromo-2-methyl-1-[4-(methylthio)phenyl]-

Participants

Reaction Steps

369.2 g (1.9 mols) of 2-methyl-1-[4-(methylthio)phenyl]-propan-1-one are dissolved in 400 ml of carbon tetrachloride. 303.7 g (1.9 mols) of bromine, diluted with 270 ml of carbon tetrachloride, are added dropwise slowly to this solution, with cooling, at room temperature. The dissolved HBr gas is then driven off by blowing with nitrogen. The solution is concentrated and is then reacted further as described below.
