Versuchsvorschrift

98.8 g (0.6 mol) of bromine are added dropwise to 130 g (0.62 mol) of 1-(4-chlorophenyl)-2,2-dimethyl-3-butanone in 1000 ml of chloroform at room temperature. The reaction mixture is subsequently stirred for 1 hour and is then concentrated. 174.7 g (97.3% of theory) of 4-bromo-1-(4-chlorophenyl)-2,2-dimethyl-3-butanone of refractive index nD20 1.5570 are obtained.

Aufarbeitung
