Versuchsvorschrift
343.2 g (1.0 mol) of 4,4,4-tribromobutyric acid chloride are dissolved in 600 g of thionyl chloride, and 266.0 g (2.0 mols) of N-chlorosuccinimide are added in portions at 60° C., whilst at the same time exposing the mixture to a high-pressure mercury lamp. After all of the N-chlorosuccinimide has been added, the resulting mixture is stirred for 5 hours at 60° C., with exposure to the said lamp. The thionyl chloride is then distilled off and the residue is rectified under a high vacuum. 309.7 g (82% of theory) of 2-chloro-4,4,4-tribromobutyric acid chloride with a boiling point of 59° to 63° C./0.05 mm Hg are obtained.
