The photopolymerization of heptadeca-2,4-diynylferrocenecarboxylate in the monolayer on a water surface was investigated by studying pressure–area isotherms and electronic spectra; the polymerization behaviour was found to depend markedly on the molecular packing in the monolayer.

Cleavage of long-chain 2-methyl-3,5-alkadiyne-2-ols in anhydrous benzene in the presence of KOH (Favorsky retroreaction) is accompanied by migration of the triple bonds and it affords 2,4-alkadiynes. Proton-donor additives (alcohol or water) completely suppress the isomerization process and enable preparation of terminal acetylenes in high yields.
