Water → 1-(Ethylsulfanyl)hept-1-ene

Participants

Reaction Steps

A mixture of 1,1-di(ethylthio)-heptane (54.5 g., 10.25 mole) and 10 drops of 89% phosphoric acid is heated in a Claisen flask at a pressure of 200-250 mm. Care is taken that the vapor temperature does not exceed 165°. The receiver is cooled with water so that ethanethiol does not condense. The distillate is diluted with ether and washed with 2 N sodium hydroxide and water and dried. Distillation (87°-90°/12 mm.) afforded 1-ethylthio-1-heptene (30 g., 78%), nD20 1.4760.
