Bromine → 1-Bromo-3,3-dimethyl-4-phenylbutan-2-one

Participants

Reaction Steps

100 g (0.57 mol) of 3,3-dimethyl-4-phenylbutan-2-one (Example 5) are dissolved in 0.8 liter of chloroform, and 29 ml (91.9 g; 1.14 mols) of bromine are added slowly at room temperature. The mixture is stirred for a further hour at room temperature and is concentrated. 145.5 g (quantitative) of 1-bromo-3,3-dimethyl-4-phenylbutan-2-one are obtained, and this directly reacted further, without isolation. ##STR24##
