Versuchsvorschrift

1-Bromo-4-(ethylthio)benzene (0.5 g, 2.3 mmol) was added to a stirred mixture of magnesium turnings (1.96 g, 82 mmol) in THF (10 mL). 1,2-Dibromoethane (30 μL) was then added and the mixture was heated at reflux to initiate the reaction. A solution of 1-bromo-4-(ethylthio)benzene (18.2 g, 84 mmol) in THF (60 mL) was added at such a rate to maintain the reaction mixture at gentle reflux. The reaction mixture was then stirred at 50° C. for 90 min and cooled to ambient temp to give a 1.16M solution of 4-(ethylthio)phenylmagnesium bromide in THF which was used in the next reaction.
