HCID 7411Benzal chlorideYield 74%

Procedure

19.5 g (0.1 mole) of benzotrichloride, 18 g (0.2 mole) of butanethiol and 0.2 g of copper-I bromide were heated to the reflux temperature, while stirring, and were left to react until the evolution of hydrogen chloride had ended (duration: 6 hours). The mixture was then subjected to fractional distillation to give 11.9 g (74%) of benzal chloride at a boiling point of 102°-106° C./30 mbar.
