中文摘要：

由听碘交换方法论的 polyfluorinated 乙烯基 stannanes 的直接 iodination 被完成给(Z)-- fluoro -- trifluoromethyl 乙烯基碘化物 stereospecifically。从撤退电子的组在 R 组把取代者改变到捐赠电子的组从 78% ～ 90% 在收益导致了增加，当它从帕拉被移动到反应没负担得起的元位置时在收益(90% ～ 95%) 的一个戏剧的变化。另外，这反应能也与杂环的组一起被用于乙烯基 stannane。与(Z) 包含杂环的一半的准备乙烯基碘化物的进一步的联合反应 -- fluoro -- trifluoromethylstannanes 与 2E,4E 选择给了 polyfluorinated 杂环的 alkadienes。

英文摘要：

The direct iodination of polyfluorinated vinyl stannanes by tin-iodine exchange methodology was achieved giving （Z）-α-fluoro-β-trifluoromethyl vinyl iodides stereospecifically. Changing the substituent in R group from the electron-withdrawing group to electron-donating group led to an increase in the yield from 78% to 90%, while it was moved from para to meta position the reaction did not afford a dramatic change in the yield （90% to 95%）. In addition, this reaction also can be applied to the vinyl stannane with heterocyclic group. The further coupling reaction of prepared vinyl iodide containing heterocyclic moiety with （Z）-α-fluoro-β-trifluoromethylstannanes gave polyfluorinated heterocyclic alkadienes with 2E,4E-selectivity.
