(E)-Enynyldialkylboranes, thus obtained, gave regio- and/or stereospecifically defined corresponding conjugated alkynones by alkaline hydrogen peroxide oxidation, conjugated (E)-enynes by protonolysis with acetic acid, and conjugated enynes bearing an unsaturated group on the internal alkenyl carbon atom by bis(acetylacetonato)copper-catalyzed cross-coupling reaction with allyl bromide or 1-bromo-1-hexyne respectively

Internal enynyldialkylboranes give regio- and stereospecifically designed conjugated enynes, bearing an allyl or 1-alkynyl group on the internal alkenyl carbon atom, by a coupling reaction with allyl bromide or 1-bromo-1-alkynes.
