文摘

An inverse trans influence has been observed in a high-valent U(V) imide complex, [((^AdArO)₃N)U(NMes)]. A thorough theoretical evaluation has been employed in order to corroborate the ITI in this unusual complex. Computations on the target complex, [((^AdArO)₃N)U(NMes)], and the model complexes [((^MeArO)₃N)U(NMes)] and [(NMe₃)(OMe₂)(OMe)₃U(NPh)] are discussed along with synthetic details and supporting spectroscopic data. Additionally, the syntheses and full characterization data of the related U(V) trimethylsilylimide complex [((^AdArO)₃N)U(NTMS)] and U(IV) azide complex [((^AdArO)₃N)U(N₃)] are also presented for comparison.
