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.
本发明公开了一种新型的烯-炔化合物Z-12-十七烯-1-炔,其结构式为CH.sub.3 (CH.sub.2).sub.3 CH.sup.(Z) =CH(CH.sub.2).sub.9 C=CH,可用作合成多种具有昆虫鳞翅目物种性信息素活性的二烯化合物的中间体,例如E,Z-2,13-十八烷二烯酸乙酯和E,Z-2,13-十八烷二烯醛,这些化合物在2-和13-位置具有两个双键。该创新化合物可通过1-溴-Z-10-十五烯与分散在有机溶剂中的乙炔钠在液氨存在下反应合成。
