high‐yielding protocol for the palladium‐catalyzed silylation of terminal alkenes is reported. This method allows facile conversion of styrenes to E‐β‐silyl styrenes by using iodotrimethylsilane (TMSI) or chlorotrimethylsilane/lithium iodide (see scheme). Terminal allyl silanes with good E/Z ratios are also readily accessed from α‐olefins.
安装硅很容易!报道了钯催化的末端烯烃硅烷化的高产率方案。该方法可以通过使用碘三甲基硅烷 (TMSI) 或氯三甲基硅烷/碘化锂轻松将苯乙烯转化为E -β-甲硅烷基苯乙烯(参见方案)。具有良好E / Z比的末端烯丙基硅烷也很容易从 α-烯烃中获得。
