与后来过渡金属的许多酰亚胺配合物相比，亚胺基二茂络合物 (Cp2Zr NR(THF)) 具有丰富的反应化学性质。简要描述了这些化合物的合成和结构特征，以及茂金属-亚氨基相互作用的定性分子轨道描述。亚胺基二茂络合物在 Zr = N 键上与各种 X-H 键发生反应，并与各种不饱和有机和有机金属化合物发生总体 [2 + 2] 环加成反应。本文介绍了详细介绍这些反应的范围和机制的研究结果，以及在催化加氢胺化、亚胺复分解和不对称转化中的应用。 (C) 2002 日本化学杂志 Forum 和 Wiley periodicals, Inc.
Imidozirconocene complexes (Cp2Zr NR(THF)) possess a rich reaction chemistry, in contrast to many imido complexes of later transition metals. The synthesis and structural characteristics of these compounds are briefly described, along with a qualitative molecular orbital description of the metallocene-imido interaction. Imidozirconocene complexes react at the Zr = N linkage with a variety of X-H bonds, and undergo overall [2 + 2] cycloaddition reactions with a wide range of unsaturated organic and organometallic compounds. Results of studies detailing the scope and mechanism of these reactions are presented herein, along with applications to catalytic hydroamination, imine metathesis, and asymmetric transformations.
