A highly selective and potentially general methodology for the synthesis of conjugated E,E- and E,Z-dienes, E-enynes, and E-1,2,3-butatrienes via hydroboration of alkynes is reported.The observed stereoselectivity was >98-99percent.
STEREO- AND REGIOSPECIFIC SYNTHESES TO PROVIDE CONJUGATED (E, Z)- AND (Z,Z)-ALKANIDES, AND ARYLATED (Z)-ALKENES IN EXCELLENT YIELDS VIA THE PALLADIUM-CATALYZED CROSS COUPLING REACTIONS OF (Z)-1-ALKENYLBORONATES WITH 1-BROMOALKENES AND ARYL IODIDES

Titled alkadienes are obtained in excellent yields stereo- and regiospecifically by cross-coupling between (Z)-1-alkenylboronates and (E)- or (Z)-1-bromoalkenes in the presence of a catalytic amount of Pd(PPh3)4 and sodium ethoxide.
