  铱催化的五元杂芳烃的硅烷基化：吡啶基-咪唑啉配体的高空间位源选择性。

  摘要：

  由于键角不同，取代基对五元环的空间效应不如六元环上的空间效应明显。因此，在许多情况下，由空间效应决定的选择性（例如 C-H 键的硼化）发生的五元杂芳烃反应的区域选择性很差。我们报道，当由 [Ir（cod）（OMe）]2 （cod=1,5-环辛二烯） 和菲咯啉配体或新的吡啶基-咪唑啉配体的组合催化时，五元环杂芳烃的硅烷化以高空间衍生的区域选择性发生，进一步增加区域选择性。在这些催化剂的硅烷基化反应中，在这些环最空间可及的 C-H 键处官能化产生高产率的杂芳基硅烷，条件是 C-H 键与先前报道的催化剂的硼基化形成产物或不稳定的产物混合物。杂芳基硅烷产物经过交叉偶联反应和取代反应，具有 ipso 选择性，生成带有卤素、芳基和全氟烷基取代基的杂芳烃。
