Water → 8,10-Dodecadien-1-ol

Temperature

95 °C

8,10-dodecadienyl bromide (1.0 g, 4.08 mmol), prepared as described above, was dissolved in N-methylpyrrolidinone (0.96 mL) under Ar-atmosphere, and 50% NaOH (0.22 mL, 4.18 mmol) was added via syringe. The reaction mixture was heated to 95° C. for 4 hrs. A colourless precipitate was observed. After cooling to room temperature, water (10 mL) was added and the resulting mixture was extracted with heptane (3×6 mL). The resulting organic phase was washed with water (10 mL) and dried (Na2SO4). Evaporation of the solvent from the organic phase gave the 8,10-dodecadienol product as a yellow liquid (487 mg, 66%).
