The palladium-catalyzed cross-coupling reaction of air-stable potassium (E)- and (Z)-alkenyltrifluoroborates with either (E)- or (Z)-alkenyl bromides allows a stereoselective synthesis of conjugated dienes in moderate to excellent yields. A variety of functional groups are tolerated in both coupling partners.
