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) CH3(CH2)9CH=CH(CH2)2x (I) wherein X is a halogen atom, are used as raw materials for the preparation of cis-olefin compounds. |
