  教旧碳阳离子新技巧：乙烯基阳离子的分子间 C-H 插入反应

  摘要：

  硅为乙烯基阳离子铺平道路 饱和碳中心通常通过碳-卤素键或碳-氧键的初始裂解发生取代反应，从而使碳带正电。事实证明，从参与双键的乙烯基碳中很难接触到类似的阳离子。Popov 等人现在表明，硅阳离子与非配位阴离子配对可以在环境条件下从这种乙烯基碳中拉出三氟甲磺酸基团（参见 Kennedy 和 Klumpp 的观点）。所得乙烯基阳离子通过 C-H 插入与简单烷烃反应。理论和机理研究表明，这些反应通过非经典途径进行，这些途径在过渡态后分叉。科学，本期，第 381 页;另见第 331 页硅阳离子从烯烃中吸出三氟甲磺酸取代基，形成乙烯基阳离子，通过 C-H 插入与烷烃反应。在过去的五十年里，乙烯基碳阳离子一直是广泛的实验和理论研究的主题。尽管在化学领域有着悠久的历史，但乙烯基阳离子在化学合成中的效用一直受到限制，大多数反应性研究都集中在溶解反应或分子内过程上。在这里，我们报告了通过硅烷弱配位阴离子催化
