The four geometrical isomers of 1,3,5-undecatriene, 1a–d have been prepared (stereospecifically and non-stereospecifically), using either (1) the Wittig reaction, (2) thermal sigmatropic hydrogen shifts, (3) partial reduction of triple bonds by zinc, or (4) organocopper reagents. The thermal behaviour of the four 1,3,5-undecatrienes has been investigated and the products formed have been characterized
1,3,5-十一碳三烯1a-d的四个几何异构体(立体比和非立体比)已经制备,可以使用(1)Wittig反应,(2)热σ氢位移,(3)部分还原锌的三键,或(4)有机铜试剂。研究了四个1,3,5-十一碳烯的热行为,并对形成的产物进行了表征。为了证实它们的构型分配,已经讨论了1a–d以及相关化合物的光谱。
