Preparation of thiophene

Preparation of thiophene

A 1.9 g (0.038 mole) sample of diacetylene was passed in the course of 75 min through a vigorously stirred mixture of 20.0 g (0.083 mole) of sodium sulfide (Na2S · 9H2O), 4.5 g (0.08 mole) of potassium hydroxide, and 65 ml of DMSO heated to 55 °C. Distillation of the reaction mixture gave 3.0 g (94%) of thiophene.
