The palladium-catalyzed arylation reaction has been employed to prepare a variety of mono- and diaryl 1,3-dienes and 1,3,5-trienes.The yields were good when electron withdrawing substituents were present in the aryl groups but only poor to fair when electron-donating groups were involved.Monoaryl dienes and trienes reacted well with all types of aryl halides to give mixed diaryl derivatives. 2-Bromostyrene reacts with phenylhexatriene to form 1,8-diphenyloctatetraene and with hexatriene to form 1,10-diphenyldecapentaene, but both only in about 15percent yield.

Bromo- or iodobenzene has been reacted with 1,4-pentadiene, (Z)- or (E)-1,4-hexadiene, and 2-methyl-1,4-pentadiene in the presece of piperidine and a palladium acetate-tri-o-tolylphosphine catalyst. 1-Phenyl-5-piperidino-3-alkenes are major reaction produ
