Komponenten

Versuchsvorschrift

1 equivalent of 1-iodo-4-nitrobenzene (IV) and 4-bromobenzenethiol (or a corresponding 4-substituted-benzenethiol) (V) were dissolved in EtOH. 8 equivalents of sodium bicarbonate were added and the mixture was stirred at reflux for 22 hours. The solvent was removed and the residue was suspended in water. The precipitate was filtered and washed with 1 M sodium hydroxide and water. The final product was obtained after re-crystallization from ethanol/water (yield: 60%).
