isomeric tetradecynoic acids were isomerized with the sodium salt of 1,2-diaminoethane. Isomers having the triple bond near the carboxyl group rearranged to E,Z-3,5- and E,E-3,5-tetradecadienoic acids (1 and 2), the former compound being the sex pheromone of the black carpet beetle. Isomers having the triple bond closer to the terminus of the chain afforded some 13-tetradecynoic acid along with 1 and 2
许多异构的十四烷酸与 1,2-二氨基乙烷的钠盐异构化。在羧基附近具有三键的异构体重排为 E,Z-3,5- 和 E,E-3,5-十四碳二烯酸(1 和 2),前一种化合物是黑地毯甲虫的性信息素。具有更靠近链末端的三键的异构体与 1 和 2 一起提供了一些 13-十四烷酸。认为离域阴离子 12 和 13 有助于形成 1 和 2。
