Uranium tris(imido) species bearing trans-imidos are desirable synthons as they can be used to mimic reactivity of more complicated uranium oxide polymeric systems. Such systems are advantageous as they are easily soluble in organic solvents, making them amenable to standard characterization methods and ligand substitution strategies. Our group has previously shown that uranium tris(imidos), easily synthesized from [(MesPDIMe)U(THF)]2 and various azides, feature axial imido substituents exhibiting differing bond characteristics than the adjacent equatorial imido substituents. The aim of this work is to show that multiple analogues of mixed imido products can be formed from either the aforementioned dimer or stable tris(imido) synthons by exploiting reactivity differences between the axial and equatorial positions. Characterization of the products was achieved via H1 NMR, IR, and elemental analysis. X-ray crystallography was used when possible to confirm molecular structures.
