A series of functionalised 2,2′:6′,2″-terpyridine ligands, each with a closo-1,2-C2B10H10R (R=H or SitBuMe2) substituent in the 4′ position, either directly or indirectly attached to the heterocyclic ring, has been prepared; two members of the series, 4′-(3-ortho-carboranylpropoxy)-2,2′:6′,2″-terpyridine (4) and 4′-(ortho-carboranyl)-2,2′:6′,2″-terpyridine (7) have been characterised by X-ray crystallography
一系列官能化2,2':6',2“ -三联吡啶配体,每一个闭合碳-1,2--C 2乙10 ħ 10 R(R = H或Si吨BuMe 2)的取代基在4'位已经制备了直接或间接连接到杂环上的化合物;该系列的两个成员4'-(3-邻-甲碳烷基丙氧基)-2,2':6',2 ''-吡啶(4)和4'-((邻-甲碳烷基)-2,2':6',X射线晶体学表征了2″-叔吡啶(7)。配体(反应7)与醇导致的硼脱帽closo-笼并产生两性离子氨基-簇官能化的配体。在三联吡啶结构域与钌(II)配位的配合物中,已观察到了碳甲环笼的类似变化。然而,如果在Si不发生脱帽吨BuMe 2 -保护的carbaborane笼被并入三联吡啶配体。
