Versuchsvorschrift

A solution of 20 ml (0.2 mol) of thiophenol and 50.6 g (0.22 mol) of 1,5-dibromopentane in 200 ml of ethanol is heated to 40° C whilst stirring and 40 ml (0.2 mol) of 5N NaOH are added dropwise. Thereafter the mixture is stirred for 2 hours and after standing overnight the alcohol is evaporated in vacuo, the residue is extracted with methylene chloride and the extract is washed 3 to 4 times with water, dried and evaporated. A yellow oil is obtained in quantitative yield.
