Hexa-2,4-diynal, octa-2,4-diynal, and octa-2,4,6-triynal (R[CC]n·CHO) dimerise in concentrated solution with evolution of carbon monoxide, to give products of the type R[CC]n– 1·CHC(CHO)·[CC]nR; above 100° even phenylpropargyl aldehyde reacts analogously. Both geometrical isomers of the ‘dimers’ were detected and characterised.
在浓溶液中随着六氧化二碳的逸出,六(2,4-二炔),八(2,4-二炔)和八(2,4,6-三炔)(R [CC ] n ·CHO)二聚,得到类型R [C C] n – 1 ·CH C(CHO)·[C C] n R;高于100°时,甚至苯基炔丙基醛也会发生类似反应。“二聚体”的两个几何异构体均被检测并表征。
