Versuchsvorschrift
For example, 5-hexenoic acid or an ester of 5-hexenoic acid (e.g. methyl 5-hexenoate, ethyl 5-hexenoate, etc.) could be used instead of 1-hexene, but the synthesis would entail a reduction of a carboxylic acid or an ester to an alcohol followed by acetylation. These syntheses are respectively shown in FIGS. 6 and 7. With reference to FIGS. 6 an 7, the 5-hexenoic acid or 5-hexenoate is reacted with 5-decene to form 5-decenoic acid or 5-decenoate, respectively, in the presence of Grubbs' catalyst and under vacuum. The resulting 5-decenoic acid or 5-decenoate are then reacted with 1-hexene, reduced, and acetylated to form 5-decenyl acetate. In addition, synthesizing 5-decenoic acid would have advantages because the salt of 5-decenoic acid could be recrystallized to increase the trans-isomer to greater than 90 percent trans-5-decenoic acid, which is then reduced and acetylated to greater than 90 percent trans-5-decenyl acetate.
