摘要：

Several new synthetic routes to the sterically crowded (C5Me5)(3)U complex have been developed. (C5Me5)(3)U can be prepared by (a) reaction of [(C5Me5)(2)UH2](2) with tetramethylfulvene, (b) reduction of (C5Me5)(2)Pb with (C5Me5)(2)UH(DMPE), (c) reaction of [(C5Me5)(2)U- (L)](+) (L = THF, DMPE) with K(18-crown-6)(C5Me5), and (d) reaction of [(C5Me5)(2)U][BPh4] with KC5Me5. Reaction of (C5Me5)(2)UH(DMPE) with C8H8 forms the product of the (C5Me5)(3)U/C8H8 reaction, [(C8H8)(C5Me5)U](2)(C8H8). The X-ray crystal structures of the (C5Me5)(2)U-[N(SiMe3)(2)] and [(C5Me5)(2)U][BPh4] precursors used in this study are reported, as well as the convenient synthesis of a new trivalent uranium precursor, (C5Me5)(2)UMe2K.
