  Dimerisation versus polymerisation: Affects of donor position in isomeric dilithium diamine-bis(phenolate) complexes

  摘要：

  The synthesis and structures of isomeric lithium diamine-bis(phenolate) complexes are reported. Deprotonation of the ligands, H2O2NN'tBu [Me2NCH2CH2N(CH2ArOH)(2), Ar = 3,5-C6H2-Bu-t(2)] and H2O2N2tBu [HOArCH2NMeCH2CH2NMeCH2ArOH, Ar = 3,5-C6H2-Bu-t(2)] in diethyl ether affords base-free lithium complexes Li2O2NN'tBu (1) and Li2O2N2tBu (2) upon solvent removal. The dioxane adduct of (1) exhibits a polymeric structure in the solid-state, whereas the dioxane adduct of (2) possesses a dimeric structure. The syntheses of K2O2NN'tBu (3), K2O2N2tBu (4), Zr(O2NN'(tBu))Cl-2 (5) and Y(O2NN'(tBu))Cl(THF), (6), are also reported. The transition metal complexes were isolated in good yields via salt metathesis reactions using 1 or 3. (c) 2005 Elsevier B.V. All rights reserved.

  Reaction of the zirconium tetrachloride with one equivalent of the sodium salt of the diamine bis (phenolate) ligand, L1H2 (Me2NCH2CH2N-(CH2-2-OH-3,5-tBu-C6H2)2) or L2H2 (Me2NCH2CH2N-(CH2-2-OH-3,5-tBu-C6H2)(CH2-2-OH-C6H4)) in the presence of air led to formation of [Lig1ZrCl]2(μ-O) and [Lig2ZrCl]2(μ-O), respectively. These novel oxo-bridged dinuclear zirconium complexes were characterized by elemental
