Vinyl halides react with disubstituted acetylenes in the presence of the palladium-formate reducing system to give stereoselective formation of functionalized 1,2,4--trisubstituted-1,3-dienes in good to high yield. With arylethynyl,dialkylcarbinols this

Not a Diels-Alder reaction but a 1,4-hydrovinylation takes place on treatment of 1,3-dienes with functionalized alkenes in the presence of the catalyst system [CoBr (dppe)]/ZnI /Bu NBH (dppe = 1,2-bis(diphenylphosphanyl)ethane). With this reaction the 1,4-dienes with different substituents R -R can
