(C5Me5)2U(O-2,6-iPr2-C6H3)(THF) (5) with copper(I) iodide affords the corresponding tetravalent uranium diiodide, amide iodide, and aryloxide iodide complexes (C5Me5)2UI2 (2), (C5Me5)2U[N(SiMe3)2](I) (6), (C5Me5)2U(NPh2)(I) (7) and (C5Me5)2U(O-2,6-iPr2-C6H3)(I) (8), respectively. This protocol was also extended to the synthesis of the alkyl iodide complex (C5Me5)2U(CHPh2)(I) (10). The isolation of complex 10
