Benzoyl Peroxide → 7-Thia-tetradecan-5-ene-1-ol

反応手順

To 1.332 gr (10 mmol) of n-heptyl mercaptan and 981 mg (10 mmol) of 5-hexyn-1-ol dissolved in 25 ml of heptane under an argon atmosphere was added a few crystals of dibenzoyl peroxide. The reaction was stirred magnetically and heated to reflux for 18 hours. It was then cooled and poured into 25 ml of 10% sodium bicarbonate and extracted with 3×25 ml of ethyl acetate. The organic phases were combined and dried over sodium sulfate, filtered, and evaporated to yield a yellow oil. The oil was chromatographed on eight silica gel type GF preparative plates, using hexane-ethyl acetate (4:1) as developing solvent. Following removal of the band corresponding to product from the plates, the product was extracted from the silica with methanol, 684 mg (30% yield) of pure 7-thia-tetradecan-5-ene-1-ol was obtained as a pale yellow oil.
