摘要：

A study was conducted to demonstrate new approach to investigate actinide metallocene reaction chemistry. Actinide metallocene reaction chemistry had the benefit of having the reactive ligands tethered within the complex. The tethered ligand platform was generated for uranium by two C-H bond activation involving the (C5Me4SiMe3)- ligand. The synthesis of a bis(tethered alkyl) complex was described along with two representative insertion reactions that showed it provided crystallographic data with [(C5Me5)2UX2] complexes and enhanced reactivity over the untethered analogues. The resulting bis(tethered alkoxide) and bis(tethered iminoacyl) complexes showed that this system provided a general entry into uranium reactivity studies by using tethered ligands.
