Our laboratory has recently demonstrated the synthesis of uranium imido [U(NR)<sub>x</sub>] complexes bearing one, two, three, or four imido ligands in the absence of ancillary ligands using organoazides and a strong reductant. These complexes show unique electronic structures, in that loading multiple imido substituents on a single metal center results in very activated U=N bonds. This strategy represents a useful method by which uranium-element multiple bonds can be activated. These materials are useful building blocks, and have been used to synthesize the first metal pentakis(imido) species, which has been spectroscopically and structurally characterized.
