Versuchsvorschrift

1,2-Dibromohexane (1.22 g, 5.0 mmol) was added to a solution of 0.6 g (5 mmol) of sodium sulfite in 20 mL of a 1:1 mixture of water and ethanol, and the resulting mixture was refluxed for 24 hours with vigorous stirring. The ethanol was then removed by distillation and the residual solution was allowed to stand at room temperature, whereupon white crystals precipitated. The crystals were filtered off under reduced pressure, washed with ether and dried to give 0.67 g (2.5 mmol) of the desired substance, namely sodium 2-bromohexylsulfonate (yield 50%).
