Bis(pentamethyIcyclopentadienyl) thorium and uranium chloro-dialkylamides and bis(dialkylamides) were prepared from the corresponding dichlorides (6,31) by the route of equation (13). The highly air-sensitive new compounds... 

The convenient preparation of thiolates of titanium " and uranium from their respective dialkylamides, but not from alkoxide analogues, demonstrates the oxophilic nature of these metals in their higher oxidation states. 

The H NMR spectra of the U" species show substantial isotropic shifts, and variable temperature experiments indicate restricted rotation around the U-N bond. The bis(dialkylamides) undergo stepwise migratory CO insertion to yield mono- and bis-carbamoyl derivatives. A large number of organouranium imido complexes with different uranium oxidation states IV and VI have been synthesized (Arney et al. 1992, Arney and Burns 1993, 1995) by both metathesis and direct protonation routes (scheme 16).
