Summary

Compounds (RC₅H₄)₃U(t-Bu) were prepared for R = H, Me, Et. Their decomposition products in aromatic solvents are consistent with a radical decomposition pathway induced by solvent-assisted U-C bond homolysis. NMR was used to study the reactions of (RC₅H₄)₃UCl with t-BuLi (R = t-Bu, Me₃Si). Reactions of (MeC₅H₄)₃U(t-Bu) with Lewis bases and fluorocarbons were studied. Analogous reaction chemistry between (RC₅H₄)₃ThX systems and t-BuLi was also studied, and reactivity differences between U and Th are discussed. Synthesis of sterically crowded (RC₅H₄)₄U compounds is next considered. Reaction of the trivalent (RC₅H₄)₃U with (RC₅H₄)₂Hg results in formation of (RC₅H₄)₄U. Steric congestion, cyclopentadienyl ligand exchange, and electron transfer are discussed. (DLC)
