New reactions of uranium amide complexes leading to pentavalent and cationic derivatives

Abstract

Protonolysis of U–N bonds in a series of uranium amide complexes by means of NEt₃HBPh₄ gives the corresponding cationic compounds, whereas oxidation of anionic U^IV amide complexes by TlBPh₄ affords the related pentavalent derivatives; thus the U^V compounds [U(NEt₂)₅], [U(cot)(NEt₂)₃] and [U(cot)(NEt₂)₂(thf)][BPh₄] have been prepared (cot =η-C₈H₈, thf = tetrahydrofuran).
