Procedure

107 g (0.269 mole) of 1-(4-chlorophenoxy)-4,5-dibromo-3,3-dimethyl-2-pentanone are dissolved in 400 ml of chloroform. 43 g (0.269 mole) of bromine are added dropwise at room temperature such that the solution is always decolorized. The mixture is then subsequently stirred at room temperature for 30 minutes, washed with water, dried over sodium sulphate and concentrated. 128 g (99% of theory) of 1-(4-chlorophenoxy)-3,3-dimethyl-1,4,5-tribromo-2-pentanone of refractive index nD20 1.5472 are obtained. ##STR107##
