Participants

Reaction Steps

A mixture of 40.5 g (0.2 mole) of 1-dodecanethiol (laurylmercaptan) in 19.2 g (0.4 mole) of sodium hydride (50% in oil) in 1 liter of toluene is refluxed with stirring for 1 hour then cooled to room temperature. To the mixture 32.5 g (0.2 mole) of 5-chloro-2-thiophenecarboxylic acid is added and the mixture is refluxed with stirring for 24 hours after which the mixture is cooled to room temperature and acidified with 5% aqueous hydrochloric acid. Water is added, and the toluene layer is separated, dried over sodium sulfate and evaporated to give 5-(dodecylthio)-2-thiophenecarboxylic acid.
