    摘要:
    This work demonstrates that the oxidation state and chemistry of uranium hydrides can be tuned with temperature and the stoichiometry of phenylsilane. The trivalent uranium hydride [(C5Me5)(2)UH](x) (5) was found to be comprised of an equilibrium mixture of U(III) hydrides in solution at ambient temperature. A single U(III) species can be selectively prepared by treating (C5Me5)(2)UMe2 (4) with 2 equiv of phenylsilane at 50 degrees C. The U(III) system is a potent reducing agent and displayed chemistry distinct from the U(IV) system [(C5Me5)(2)U(H)(-H)](2) (2), which was harnessed to prepare a variety of organometallic complexes, including (C5Me5)(2)U(dmpe)(H) (6), and the novel uranium(IV) metallacyclopentadiene complex (C5Me5)(2)U(C4Me4) (11)

Consequently, very different reactivity patterns emerge, e.g., 2 can act as a source for the (η(5)-C5Me5)2U(II) fragment when reacted with alkynes and a variety of heterounsaturated molecules such as imines, bipy, carbodiimide, organic azides

    The first example of an f-element ketimido complex has been prepared. Complex 2 is surprisingly unreactive and displays unusual electronic properties. The physical properties and chemical stability of this complex suggest higher U-N bond order due to significant ligand to metal pi-bonding in the uranium ketimido interactions.
