摘要

(E)-α-Stannylvinyl phenyl(or p-tolyl)sulfones underwent an iododestannylation reaction to afford (E)-α-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.
