  Coupling of Aromatic N-Heterocycles Mediated by Group 3 Complexes

  摘要：

  Group 3 eta(2)-N,C-pyridyl complexes supported by a ferrocene-diamide ligand have been known to mediate the coupling of eta(2)-N,C-pyridyl and coordinated-pyridine ligands with a concomitant dearomatization of the pyridine ligand. Examples reported previously by us were limited to a few cases. In order to investigate the scope of the Coupling reaction, various eta(2)-N,C-pyridyl scandium complexes were isolated and characterized. Their reactivity toward other aromatic N-heterocycles is presented along with the characterization Of file Subsequent reaction products. The coupling reaction is favored by ortho substitution, the presence of fused aromatic rings on the pyridine ligand, and chelating substrates. In one instance, the product of the coupling reaction between a scandium eta(2)-N, C-pyridyl complex and 7,8-benzoquinoline could not be isolated because a subsequent isomerization reaction was favored. The coupling reaction is not restricted to eta(2)-N,C-pyridyl fragments, and it proceeds also from CH, groups bound to the metal center and connected to a pyridine ligand. The reaction between eta(2)-N,C-imidazolyl scandium complexes and 2,2'-bipyridine is also discussed.

  二茂铁二酰胺配体支持的钪吡啶基配合物的插入反应

  摘要：

  摘要与早期过渡金属 η2(N,C)-吡啶基配合物的报道实例不同，由二茂二酰胺配体支持的钪 η2(N,C)-吡啶基配合物与吡啶进一步反应生成偶联产物。尽管它们与不饱和底物的大多数插入反应与之前的茂金属和二茂锆配合物的插入反应相似，但在与丁二烯的反应中，观察到的反应性高于所报道的茂金属配合物的反应性。本文讨论了由 1,1'-二茂铁二酰胺配体支持的 η2(N,C)-吡啶基钪配合物与乙烯、2-丁炔和 1,3-丁二烯的反应。
