Versuchsvorschrift

Ten grams (0.072 mole) of 3-hydroxy-6,6-dimethyl-hept-1-ene-4-yne was dissolved in 100 ml of hexane, and to the resulting solution were added 50 mg (6.8×10-4 mole) of N,N-dimethylformamide and 12.80 g (0.108 mole) of thionyl chloride. The mixture was reacted overnight at room temperature with stirring with a hydrogen chloride gas trap mounted on the reactor. The reaction mixture was concentrated under reduced pressure to obtain 10 g of a crude 1-chloro-6,6-dimethylhept-2-ene-4-yne.
