Versuchsvorschrift
A mixture of 50 g. of sec.-myrcenol (prepared according to the method described in paragraph b) above), 300 g. of n-butyl vinyl ether, 1 g. of mercuric acetate and 10 g. of sodium acetate were refluxed for 40 hours (120°) under nitrogen. During this heating period 1 g. of additional mercuric acetate was added every 6 hours. The laboratory vessel was connected to a downward directed condenser, and the excess of n-butyl vinyl ether was distilled under ordinary pressure. The residue was distilled under vacuum. A yield of 75% of 4-methyl-8-vinyl-4,8-nonadienal that contained approximately 15% of unreacted alcohol was obtained. This alcohol could be recovered when the above C12 aldehyde was converted to β-sinensal.
