The invention discloses a method for preparing trans -7 and cis -9 - dodecadiene acetate, which comprises (1) adding 1 - 1 dichloroethylene in 2 - butyne tetrahydrofuran solution. The metal palladium compound, cuprous iodide and diisopropylamine undergo a coupling reaction to obtain 1 - chlorine -3 - yne -1 - hexene. (2) 20 °C (ClMgO) Under stirring, at CH. 2 )6 In MgCl, hexamethylphosphoric acid triamide and ferric acetyl acetonate are sequentially added, 1 - chlorine -3 - yne -1 - hexene is added dropwise to obtain the trans 7 - dodecene -9 - alkynol. (3) Zn powder was added to trans 7 - dodecene -9 - alkynol, stirred to obtain trans 7, cis 9 - dodecadienol, acetic anhydride and pyridine were added and stirred to obtain trans -7, cis -9 - dodecadiene acetate. The method provided by the invention is cheap and wide in source; the method has the advantages of short synthesis period, less steps, high yield, good stereoselectivity and simple post-treatment.

PROBLEM TO BE SOLVED: To provide a method capable of industrially producing a conjugated diene or a conjugated triene in a short process from a raw material which is easy to obtain and handle. SOLUTION: A conjugated diene is produced from a 3-alkenal via reactions of the following first step, second step, and third step in this order: the first step of reacting a Grignard reagent with the 3-alkenal to obtain a homoallylic alcohol; a second step of reacting an esterification reagent or a halogenation reagent with the homoallylic alcohol to obtain a sulfonic ester or a halogenated product; and a third step of having a base act on the sulfinic acid ester or the halogenated product to cause an elimination reaction.
