Participants

Reaction Steps

33 g of thiophenol were dissolved in a solution of 6.9 g of sodium in 120 ml of ethanol and the solution was added dropwise to 129 ml of 1,2-dibromoethane. The mixture was heated under reflux for 1 hour and cooled and 250 ml of ether were added. The salt which had precipitated out was filtered off. The filtrate was concentrated and the evaporation residue was fractionated. 55.4 g of a colourless oil with a boiling point of 125° to 130° C. under 12 mm Hg were obtained.
