NEW REACTIONS OF URANIUM AMIDE COMPLEXES LEADING TO PENTAVALENT AND CATIONIC DERIVATIVES

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 Uv compounds [U(NEt2)5], [U(cot)(NEt2)3] and [U(cot)(NEt2)2(thf)][BPh4] have (cot = eta-C8H8, thf = tetrahydrofuran).
