(E)- or (Z)-Enynoic acids and (2E,4E)- or (2Z,4E)-dienoic acids can be obtained in good yields under mild conditions through palladium-catalysed cross coupling of (E)- or (2)-3-iodoprop-2-enoic acid with alkynylzinc or vinyltin reagents.

The epoxy alcohol exo-6-hydroxy-exo-4-oxatetracyclo(6.2.1.0.2,703,5)-undec-9-ene (1a) was synthesized by photooxygenation of dicyclopentadiene in the presence of Ti(OiPr)4; vacuum flash pyrolysis (520 deg C) of 1a resulted in 3,4.epoxy-5-hydroxycyclopentene (2) as intermediate, wich at elevated temperature rearranged into the cis- and trans-2,4-pentadienoic acids (8).
