Uranium thiolates

Thorium and uranium thiolates coordinated by additional bulky ligands can be prepared. Reaction of the uranium metallacycle [ (Me3Si)2N 2U(CH2SiMe2NSiMe3] with one equivalent of 2,6-dimethylthiophenol allows for the isolation of monothiolate U(S-2,6-Me2C6H3)[N-(SiMe3)2]3. ""... 

The reactivity of select uranium(IV) thiolate compounds has been inyestigated. The product (SPr )2C=S was identified from reaction of carbon disulfide with U(SPr )4. ... 

Oxidation of the sterically crowded complex Cp 3U provided access to [Cp 2U]2(/i-0) as the first molecular trivalent uranium oxide. The U-O-U angle in this molecule is 171.5(6)°.85 Reduction of the uranium(iv) thiolates... 

Arhguie et al. [ 140] reported the synthesis of few uranium(III) thiolato complexes of the type Na[Cp 2U(SR)2] (where Cp = ri -CsMes R = Ph, Me, i-Pr) by the reductive reaction of their corresponding uranium(IV) bis thiolate complexes with sodiiun amalgam. It is worth mentioning here that... 

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.
