The boryl group cis to the C(3)=C(4) group in 2,4-aryl-1,1- bis(pinacolatoboryl)-1,3-butadienes undergoes Pd-catalyzed cross-coupling reaction with aryl iodides stereoselectively at room temperature, giving rise to the corresponding boronates as a single diastereomer. Subsequent coupling of the boronates with alkenyl iodides allows us to synthesize 1,3,4,6-tetraarylated 1,3,5-hexatrienes stereoselectively. Georg Thieme Verlag Stuttgart.
