从硅烷化的双吲基异丁基锆氢化物中还原消除烷烃，得到了一个具有不寻常的Eta6吲基配体的锆夹心络合物。对其与四氢呋喃的加合物进行了结晶学表征，发现其在六元环上有明显的定位。更强的配体如一氧化碳和二苯乙炔的络合有效地促进了Eta6吲哚配体的上链重排，并提供了常见的弯曲的茂锆衍生物。锆夹心化合物还经历了吡啶配体的碳氢键的氧化加成，得到了具有结晶学特征的二甲氨基吡啶氢化物锆络合物。
Reductive elimination of alkane from a silylated bis-indenyl zirconium isobutyl hydride affords a zirconium sandwich complex with an unusual eta6 indenyl ligand. Crystallographic characterization of its adduct with tetrahydrofuran has been achieved and reveals significant localization in the six-membered ring. Complexation of more potent ligands such as carbon monoxide and diphenylacetylene are effective in promoting haptotropic rearrangement of the eta6 indenyl ligand and provides familiar bent zirconocene derivatives. The zirconium sandwich compound also undergoes oxidative addition of carbon-hydrogen bonds of pyridyl ligands, resulting in a crystallographically characterized dimethylamino pyridyl hydride complex of zirconium.
