Versuchsvorschrift

Potassium carbonate (2.2 g) and ethyl iodide (4.3 g) were added to a solution of bis(p-hydroxyphenyl)disulfide (2.0 g) in DMF (20 ml), and the mixture was stirred at 70° C. for 16 hours and poured into ice water (100 ml). The mixture was extracted with hexane (500 ml) and concentrated to give bis(p-ethoxyphenyl)disulfide (1.8 g, 82%).
