A range of conjugated Z,Z-dienes have been prepared in a stereo-specific manner via acetylene carbocupration: the value of this procedure has been illustrated by an extremely short synthesis of hexadeca-11Z, 13Z-dienal a principle component of NavelOrangewormPheromone.

(11Z,13Z)-11,13-hexadecadienal, the female sex pheromone of the navelorangeworm (Amyelois transitella), was synthesized from commercially available 10-bromo-1-decanol in a 27% overall yield (8 steps). The synthesis was achieved by using 10-iododecanal, trimethylsilylacetylene and (Z)-1-bromo-1-butene as the key building blocks, employing Sonogashira-Hagihara coupling and Brown's hydroboration-protonolysis
