A (Z/E) - 8 - dodecene -1 - ethoxylate ester synthesis method

The invention discloses a (Z/E)-8-dodecylene-1-olacetate synthesis method. The method is characterized in that 1-halogenated pentine and magnesium 1-(2-oxotetrahydropyranyl)heptylhalide as initial raw materials undergo a coupling reaction to produce 8-(2-oxotetrahydropyranyl)dodecyne, the 8-(2-oxotetrahydropyranyl)dodecyne is subjected to hydrogenation, one-pot deprotection and esterification so that (Z)-8-dodecylene-1-olacetate and (E)-8-dodecylene-1-olacetate are obtained, wherein a mole ratio of (Z)-8-dodecylene-1-olacetate to (E)-8-dodecylene-1-olacetate is (90%-99.5%): (10%-0.5%). The method utilizes 1-halogenated pentine and magnesium 1-(2-oxotetrahydropyranyl)heptylhalide as initial raw materials, provides a novel reaction route, has a short route, produces less by-product, has simple and routine processes, is free of complex post-reaction treatment processes and improves production efficiency. The method satisfies different insect pheromone trap or lure requirements on an isomer ratio in practical application and is suitable for large-scale industrial production.
