Palladium-catalyzed stereoselective synthesis of (E,E)-1-arylselenobutadienes

(E)-Vinylic zirconium(IV) complexes, readily obtainable via hydrozirconation of alk-1-ynes, react with (E)-1-halo-2-arylselenoethylenes in the presence of catalytic amounts of tetrakis(triphenylphosphane)palladium to produce (E,E)-1-arylselenobutadienes in high yields.

Stereoselective synthesis of (E,E)-1-arylselenobutadienes by cross- coupling reactions in the presence of palladium catalyst

Hydrozirconation of arylselenoethynes 1 gives selenium containing zirconium(IV) complexes 2, which are cross coupled with alkenyl halides in the presence of Pd (PPh3)4 to afford (E,E)-1-arylselenobutadienes 4 in high yields.
