A STEREOSPECIFIC SYNTHESIS OF CONJUGATED (E,Z)-AND (E,E)-ALKADIENES BY THE PALLADIUM-CATALYZED REACTION OF (E)-1-ALKENYLBORONIC ACIDS AND 1-ALKENYL IODIDES

The reaction of (E)-1-alkenylboronic acids with (Z)-or(E)-1-alkenyl iodides in the presence of a catalytic amount of tetrakis(triphenylphosphine)-palladium and sodium hydroxide gave the corresponding conjugated (E,Z)-or (E,E)-alkadienes with high stereospecificity.
