A new efficient synthetic protocol for the highly stereoselective synthesis of unsymmetrical (or symmetrical) (E)-stilbenes and (E,E)-1,4-diarylbuta-1,3-dienes based on sequential palladium-catalyzed Heck arylation-Hiyama cross-coupling reactions using cy

A mild and general and stereospecific cross-coupling reaction of unsymmetrical 1,4-bissilyl-1,3-butadienes has been accomplished. By the use of either a benzyldimethylsilyl or 2-thienyldimethylsilyl unit at one end of the dienylsilanol, a selective cross-

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.
