摘要：

Hexa-2,4-diynal, octa-2,4-diynal, and octa-2,4,6-triynal (R[C≡C] n·CHO) dimerise in concentrated solution with evolution of carbon monoxide, to give products of the type R[C≡C] n-1·CH=C(CHO)·[C≡C]nR; above 100° even phenylpropargyl aldehyde reacts analogously. Both geometrical isomers of the 'dimers' were detected and characterised.
