A STEREOSPECIFIC SYNTHESIS OF CONJUGATED (E,Z)- AND (Z,Z)-ALKADIENES BY A PALLADIUM-CATALYZED CROSS-COUPLING REACTION OF 1-ALKENYLBORANES WITH 1-ALKENYL BROMIDES

The reactions of (Z)-1-alkenyldisiamylboranes with (Z)- or (E)-1-alkenyl bromides in the presence of a catalytic amount of tetrakis(triphenylphosphine)palladium and sodium ethoxide gave the corresponding conjugated (Z,Z)- or (Z,E)-alkadiene with high ster
