Abstract

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