Versuchsvorschrift

54 g (0.35 mole) of 2,6-dimethyl-oct-4-en-1-al are added in the course of 15 minutes to a solution of 0.4 mole of vinyl-magnesium chloride in 2 liters of tetrahydrofuran, whilst cooling with ice. After a reaction time of 30 minutes, the mixture is hydrolyzed with 40 ml of water, the organic phase is isolated and the solvent is distilled off. The reaction product is fractionated, giving 60 g of the above allyl alcohol (yield, 94% of theory). B.p. = 48°-52° C at 0.02 mm Hg; nD25 = 1.4591.
