Abstract

Treatment of UCl4 with one or two equivalents of IPr [IPr = {C(NArCH)2}, Ar = 2,6-diisopropylphenyl] gives [UCl4(IPr)2] as the sole isolable uranium-containing containing product; an X-ray diffraction study showed close Cl⋯Ccarbene contacts, but DFT analysis suggests the contacts are the result of aryl chloride steric repulsions as the Cl⋯C orbital interaction is negligible.
