We describe the synthesis by oxidative atom-transfer chemistry and structure of organouranium(V) and -(VI)complexes containing terminal oxo functional groups of the general formula (C[sub 5]Me[sub 5])[sub 2]U-(EAr)(O) (E = O (3) and N (4); Ar=2,6-diisopropylphenyl). In effect, we have extended the synthetic utility of oxidative atom-transfer chemistry to the preparation of the first complexes of uranium(V) and-(VI)containing terminal nonooxo functional groups. The structural characterization of these compounds reveals uranium oxo bond lengths longer than those typical for the uranyl ion (UO[sub 2])[sup 2+], which may reflect a reduced relative bond order. 18 refs., 1 fig.
