The palladium-catalyzed “head-to-tail” cross-coupling reaction of 1-alkenylboranes with phenyl or 1-alkenyl iodides. A novel synthesis of 2-phenyl-1-alkenes or 2-alkyl-1,3-alkadienes via organoboranes

The reaction of phenyl or 1-alkenyl iodides with 1-alkenyl-1,3,2-benzodioxaboroles readily obtainable via the hydroboration of 1-alkynes, gives the corresponding “head-to-tail” cross-coupling products, 2-phenyl-1-alkenes or 2-alkyl-1,3-alkadienes, in good yields. The reaction is effectively catalyzed by catalytic amounts of palladium compounds in the presence of triethylamine.
