The present invention relates to syntheses of 5-decenyl acetate, the major component in Peach Twig Borer pheromone, and other pheromone components. The syntheses entails few reaction steps, use commercially available starting materials, and have relatively short process times. A preferred embodiment of the syntheses involves self-metathesizing 1-hexene in the presence of Grubbs' catalyst, [(PCy3)2Cl2]Ru═CHPh. The resulting 5-decene is then reacted with an alcohol or acetate protected hexene under vacuum to yield 5-decenyl acetate. These syntheses produce good yields without the need for expensive or sophisticated equipment.
