  rare-earth-metal scandium led to the isolation of ate complex [Li(thf)4][LiSc2(CH2SiMe3)8] as the preferred crystallized product. Here, the reaction of adduct ScCl3(thf)3 and LiCH2SiMe3 was performed in Et2O/n-hexane, in the absence of additional THF. The reaction of LaCl3(thf) with 3 equiv. of LiCH2SiMe3 in THF/Et2O at −40 °C yielded the ate complex [Li(thf)4][La(CH2SiMe3)4(thf)], which is the first

  The reduction of digallane (dpp-Bian)Ga-Ga(dpp-Bian) (1) dpp-Bian = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene} with 2 equiv of sodium in Et2O affords complex (dpp-Bian)Ga-Na(Et2O)(3) (2), containing a gallium-sodium direct bond. The gallium-zinc complex with a chiral amido-imino ligand, (dpp-Bian)Ga-Zndpp-Bian(Bu-n)} (4), has been prepared by the salt elimination reaction between 2 and [dpp-Bian(Bu-n)}ZnCl](2) (3). Reduction of complex (dpp-Bian)Ga-Zn(dpp-Bian) (5) with 1 equiv of potassium gave the gallium-zinc complex [(dpp-Bian)Ga-Zn(dpp-Bian)]-[K(thf)(5.5)] (6). Lanthanum dicyclopentadienides [(C5Me4Et)(2)LaCl2]-[K(thf)(2)] (7) and [(C5Me5)(2)LaCl2][Na(Et2O)(2)] (8) react with 2 to give the first complexes with gallium-lanthanum bonds, (dpp-Bian)Ga-La(C5Me4Et)(2)(thf) (9) and (dpp-Bian)Ga-La(C5Me5)(2)(thf) (10), respectively. The newly prepared complexes 4, 6, 9, and 10 have been characterized by H-1 nuclear magnetic resonance and infrared spectroscopy; the molecular structures of 4, 6, and 9 have been determined by single-crystal X-ray analysis. The electronic structures of 4 and 10 have been examined by density functional theory calculations.

  O-Aryllithium complexes are easily prepared from stable aminophosphonium salts, and their coordination to rare-earth metals was studied. The ligand to metal ratio in the formed complexes was shown to depend exclusively on the substituent on the nitrogen atom of the ligand. Aryl lithium derivatives 3a and 3b, exhibiting bulky groups (SiMe3 and Bu-t, respectively), gave monocoordinated yttrium complexes 4a-Y and 4b-Y. On the other hand, with aryllithium 3a, possessing an isopropyl at nitrogen, complexes of Y-III, Nd-III and Gd-III with a 2:1 ligand to metal ratio could be obtained. Finally with less hindered ligands such as 6c, featuring an n-butyl substituent, triscoordinated Y, Nd, and La complexes were accessible. X-ray crystal structures have been obtained with all three stoichiometries. These complexes were employed as catalyst precursors for 1,3-butadiene polymerization using various activators. Yttrium complexes were found ineffective, but some neodymium complexes achieved highly selective polymerization of 1,3-butadiene, giving up to 95% of 1,4-cis-polybutadiene albeit with mild activity.
