摘要：

(E)-alpha-Stannylvinyl phenyl(or p-tolyl)sulfones underwent an iododestannylation reaction to afford (E)-alpha-iodovinyl phenyl(or p-tolyl)sulfones 1, which reacted with (E)-alkenylzirconium(IV) complexes 2 produced in situ by hydrozirconation of terminal alkynes in the presence of a Pd(PPh3)(4) catalyst to afford stereoselectively (1Z,3E)-2phenyl(or p-tolyl)sulfonyl- substituted 1,3-dienes 3 in good yields.
