coordinated to titanium and zirconium, producing a series of discrete metallocene derivatives with a pendant amine arm. These complexes are extremely sensitive towards moisture, but they can easily be converted into benchtop‐stable ammonium chloride derivatives. The ligands and their complexes have been fully characterized by NMR and IR spectroscopy, elemental analysis and/or high resolution ESI‐MS. The solid‐state
描述了一种新方法,其中N功能化的环戊二烯配体是通过环戊二烯酸钠的亲核取代反应合成的Katritzky's(benzotriazolyl)化合物上的。该途径使得能够引入通过亚甲基间隔基与环戊二烯基环隔开的笨重的和碱性的胺。因此,该方法代表了一般的富勒维途径的一种有价值的替代方法。所得的配体已与钛和锆配位,产生了一系列具有侧链胺臂的离散的茂金属衍生物。这些配合物对水分极为敏感,但它们很容易转化为台式稳定的氯化铵衍生物。配体及其配合物已通过NMR和IR光谱,元素分析和/或高分辨率ESI-MS进行了充分表征。
