Synthesis and reactivity of bis(imido) uranium(VI) cyclopentadienyl complexes

Liam P. Spencer, Robyn L. Gdula, Trevor W. Hayton, Brian L. Scott and James M. Boncella

The bis(imido) uranium(VI)–C5H5 and –C5Me5 complexes (C5H5)2U(NtBu)2, (C5Me5)2U(NtBu)2, (C5H5)U(NtBu)2(I)(dmpe), and (C5H5)2U(NtBu)2(dmpe) can be synthesized from reactions between U(NtBu)2(I)2(L)x (L = THF, x = 2; L = dmpe, x = 1) and Na(C5R5) (R = H, Me); these complexes represent the first structurally characterized C5H5-compounds of uranium(VI) and they further highlight the differences between UO22+ and the bis(imido) fragment.
