Disclosed are compounds suitable for use as raw materials which enable cis-olefin compounds useful as physiologically active substances such as the sex pheromones of various insects, or as intermediates for the synthesis thereof to be prepared on an industrial scale at a reasonable cost, and processes for the preparation of cis-olefin compounds by using the same. For this purpose, novel compounds (i.e., 1-halo-cis-3-tetradecenes) of the general formula (I) CH.sub.3 (CH.sub.2).sub.9 CH.dbd.CH(CH.sub.2).sub.2 X (I) wherein X is a halogen atom, are used as raw materials for the preparation of cis-olefin compounds.
本发明涉及一种适用于作为原料的化合物,可使得诸如各种昆虫的性信息素等生理活性物质或其合成中间体的顺式烯烃化合物能够以合理的成本在工业规模下制备,并使用相应的过程制备顺式烯烃化合物。为此,本发明使用具有通式(I)CH.sub.3(CH.sub.2).sub.9CH.dbd.CH(CH.sub.2).sub.2X(I)的新型化合物(即1-卤代顺式-3-十四碳烯),其中X是卤素原子,作为制备顺式烯烃化合物的原料。
