  Organoaluminum Hydroxides Supported by β-Diketiminato Ligands: Synthesis, Structural Characterization, and Reactions

  摘要：

  Three beta-diketiminato ligands (L-1 = HC[C(Me)N(Ar)](2), Ar = 2,4,6-Me3C6H2;L-2 = HC[C(Me)N(Ar)](2), Ar = 2,6-iPr(2)C(6)H(3); L-3 = HC[C(tBu)N(Ar)](2), Ar = 2,6-iPr(2)C(6)H(3)) were employed to prepare the organoaluminum hydroxides LAlR(OH) (R = Me, Et, Ph, OEt, OSiMe3) by hydrolysis of the corresponding chlorides in the presence of a N-heterocyclic carbene as HCl scavenger. Reaction of the organoaluminum hydroxide with Cp2ZrMe2 in toluene afforded the heterobimetallic oxide LAlR(mu-O)ZrMeCp2 under evolution of methane. All compounds were characterized by multinuclear NMR, IR, mass spectrometry, and elemental analysis. The structures of (LAlPh)-Al-1(OH) (10), L-2 AlPh(OH) (11), L-2 AlOEt(OH) (12), L-2 AlOSiMe3(OH) (13), and L-2 AlPh(mu-O)ZrMeCp2 (17) were determined by single-crystal X-ray diffraction studies. The polymerization of ethylene was studied with compound 17, which exhibits moderate catalytic activity.

  Hydrolysis and alcoholysis of the cyclic aluminum acyl LAl[C(O)C(SiMe3)C(SiMe3)] (1; L = HC[(CMe)(NAr)]2, Ar = 2,6-iPr2C6H3) resulted in the formation of the cyclopropenylaluminum derivative LAl[C3(SiMe3)2]C(O)C(SiMe3)C(SiMe3)} (2) with the elimination of aluminum hydroxides LAlOH(OR) (R = H, Et, tBu).

  6-diisopropylphenyl; BDI*=HC[C(tBu)N(DIPP)]2). The selectivity of alumoxane formation depends strongly on the nature of the β-diketiminate ligand, the experimental procedure and the solvent. The mononuclear alumoxanes (BDI)Al=O and (BDI*)Al=O are highly reactive intermediates that cannot be isolated but either aggregate to give less reactive dimers or decompose by internal C−H activation of a backbone Me group

  介绍了几种用 O 2、Et 3 P=O 或 N 2 O 氧化 β-二酮亚胺化 Al I配合物 (BDI)Al 和 (BDI*)Al (BDI=HC[C(Me)N(DIPP) )] 2，DIPP=2,6-二异丙基苯基；BDI*=HC[C( t Bu)N(DIPP)] 2 )。铝氧烷形成的选择性很大程度上取决于β-二酮亚胺配体的性质、实验程序和溶剂。单核铝氧烷 (BDI)Al=O 和 (BDI*)Al=O 是高反应性中间体，它们不能被分离，但要么聚集以产生反应性较低的二聚体，要么通过骨架 Me 基团或i的内部 C-H 活化而分解公关组。醚类溶剂（如 Et2O）与铝氧烷反应生成 (BDI)Al(OEt)OH 和通过 β-H 消除产生乙烯。在 N 2 O 氧化的情况下，观察到随后与第二当量的 N 2 O 反应形成次亚硝酸盐络合物 (BDI)Al(N 2 O 2 ) 和 (BDI*)Al(N 2 O
