Further investigations indicate that N,N'-diisopropylcarbodiimide does not react with complexes 1 and 2 under the same conditions; however, it readily inserts into the lithium-guanidinate ligand bond of LiN=C(NMe2)2. As a synthon of the insertion product Li[(iPrN)2C(N=C(NMe2)2)], its reaction with (C5H5)2LnCl gives the novel organolanthanide complexes containing the guanidinoacetamidinate

  • Synthesis and structures of titanium and yttrium complexes with N,N′-tetramethylguanidinate ligands: different reactivity of the M–N bonds toward phenyl isocyanate

    A salt elimination reaction of bis(cyclopentadienyl)titanium dichloride (C5H5)2TiCl2 with one equiv. of N,N′-tetramethylguanidinate lithium [LiNC(NMe2)2] proceeded in THF at room temperature to yield a bis(cyclopentadienyl)titanium mono-guanidinate chloride (C5H5)2TiCl(NC(NMe2)2) (1). However, treatment of two equiv. of LiNC(NMe2)2 with (C5H5)2TiCl2 under the same conditions resulted in the elimination of one cyclopentadienyl ring to form an unexpected mono(cyclopentadienyl)titanium bis(guanidinate) chloride (C5H5)TiCl[NC(NMe2)2]2 (2), in which only one Ti–Cl bond is broken, with the other Ti–Cl bond retained. Reaction of [(C5H5)2YCl]2 with LiNC(NMe2)2 gave the corresponding product (C5H5)2Y[μ-η1:η2-NC(NMe2)2]}2 (3). On further investigations on the reactivity of 1–3 toward phenyl isocyanate, we found phenyl isocyanate only inserts into the Y–N(μ-Gua) bonds of 3 to yield [(C5H5)2Y(μ-η1:η2-OC(NC(NMe2)2)NPh)]2 (4). Complexes 1–4 were characterized by elemental analysis and spectroscopic properties and their solid-state structures were determined by X-ray single-crystal diffraction.
