実験手順

To a solution of 42.7 g. of 1-tosyloxynon-4-en-6-yne (0.14 moles) in 150 ml. of anhydrous dimethylformamide is added 18.7 g. of sodium bromide (0.16 moles) and the mixture is heated at 75° for 2 hour and then allowed to stir overnight at room temperature. The reaction mixture is then diluted with 200 ml. of ice water and extracted with pentane. The pentane extract is washed with water and dried over sodium sulfate. Evaporation of solvent in vacuo and distillation of the residue oil gave 24.3 g. of 1-bromonon-4-en-6-yne (84% yield) b.p. 52°-55° at 0.15 mm.
