Abstract

Reactions between [(TrenTIPS)UVI[triple bond, length as m-dash]N] (1, TrenTIPS = {N(CH2CH2NSiPri3)3}3−) and [MII(η5-C5R5)2] (M/R = Cr/H, Mn/H, Fe/H, Ni/H) were intractable, but M/R = Co/H or Co/Me afforded [(TrenTIPS)UV[double bond, length as m-dash]N-(η1:η4-C5H5)CoI(η5-C5H5)] (2) and [(TrenTIPS)UIV–NH2] (3), respectively. For M/R = V/H [(TrenTIPS)UIV–N[double bond, length as m-dash]VIV(η5-C5H5)2] (4), was isolated. Complexes 2–4 evidence one-/two-electron uranium reductions, nucleophilic nitrides, and partial N-atom transfer.
