Abstract
Disclosed is a novel ene-yne compound Z-12-heptadecen-1-yne expressed by the structural formula CH.sub.3 (CH.sub.2).sub.3 CH.sup.(Z) =CH(CH.sub.2).sub.9 C=CH, which is useful as an intermediate in the synthetic preparation of several diene compounds having activity as a sex pheromone of the insects belonging to the lepidopteran order, such as E,Z-2,13-octadecadienyl acetate and E,Z-2,13-octadecadienal, having two double bonds at the 2- and 13-positions. The inventive compound can be synthesized by the reaction of 1-bromo-Z-10-pentadecene with sodium acetylide dispersed in an organic solvent in the presence of liquid ammonia.
