Monocyclooctatetraene uranium amide compounds in the +4 and +5 oxidation states

The compounds M[U(cot)(NEt2)3] 1 (cot = η-C8H8, M = Li or K) were prepared by (a) reaction of [U(NEt2)4] or [U(NEt2)3][BPh4] with K2(cot), (b) treatment of UCl4 with LiNEt2 and K2(cot) and (c) reaction of [U(cot)2] with LiNEt2. The compound [U(cot)(NEt2)2(thf)] 2 (thf = tetrahydrofuran) was synthesized by treating [U(NEt2)2Cl2] with K2(cot). Uranium(v) compounds were obtained by oxidation of 1 and 2. Treatment of 1 with TIBPh4 afforded [U(cot)(NEt2)3] which was transformed into [U(cot)(OPri)3] by alcoholysis. Complex 2 reacted with AgBPh4 or Tl(cp) (cp = η-C5H5) to give [U(cot)(NEt2)2(thf)][BPh4] and [U(cot)(cp)(NEt2)2] respectively, the crystal structure of the first of which has been determined.
