Versuchsvorschrift
A solution of 5-(triethylsilyl)-4-pentin-1-ol (416 g, 2.1 mmol) in absolute acetonitrile (20 mL was added in drops to a solution of triphenylphosphine diiodide (2.80 g, 5.4 mmol) and imidazole (1.04 g, 15.4 mmol) with argon and stirred overnight at room temperature. The raw product was purified by means of flash chromatography (38 g, 20×2.5 cm) with cyclohexane/ethyl acetate (9:1).
