  摘要：

  日期：2001.11

  The dehydration of toluene insoluble salts TbCl(3)(.)6H(2)O (1), DyCl(3)(.)6H(2)O (2) and NdCl(3)(.)6H(2)O (3) in their reaction with organoalurninum compounds (RnAlX3 (- n)): i-Bu3Al, Et3Al, Et2AlCl, EtAlCl2 and the influence of (BuO)(3)PO (TBP) on the process were studied. In the reaction of R(n)A1X(3) (- n) with the water of crystallization of salts 1-3, aluminoxanes and the following gases are formed: i-BuH for i-Bu(3)A1, EtH for Et3Al, EtH and HCl for Et2AlCl and EtAICl(2) as a result of the attack on the Al-C or AI-Cl bond independent of the presence of TBP. In the absence of TBP the salts 1-3 are dehydrated by RnAlX3 - n to give insoluble products LnCl(3)(.)0.5H(2)O(.)0.5(R2Al)(2)O, where R is alkyl for i-Bu3Al and Et3Al, or R is alkyl and Cl for Et(2)AICl. The reaction of RnAlX3 - x with 1-3 in the mixture of toluene-TBP at the ratio TBP/Ln greater than or equal to 12:1 results in the complete removal of water from LnCl(3)(.)6H(2)O and leads to the formation of homogeneous solutions, containing aluminoxanes and LnCl(3)(.)3TBP complexes. Homogeneous solutions, obtained after interaction in the system NdCl(3)(.)6H(2)O + TBP + PhMe + R3Al were then activated with either i-Bu3Al or (i-Bu2Al)(2)O and used as catalysts for polymerization of butadiene. All the catalysts were highly active for polymerization of butadiene, and produced a low-molecular polybutadiene. (C) 2001 Elsevier Science B.V. All rights reserved.

• Double coordination and activation ability of methylalumoxane (MAO) for hetero functionality: Pivotal role as polymerization cocatalyst
  作者：Hideo Hanawa、Noriko Abe、Keiji Maruoka

  DOI：10.1016/s0040-4039(99)01024-2

  日期：1999.7

  A new insight in the crucial role of methylalumoxane (MAO) as polymerization cocatalyst has been demonstrated by using typical carbonyl reduction and electrophilic alkylation by comparison with various MAO analogues, (Me2Al2)(2)O, MeAl(OPri)(2), and Me2AlOPri. Furthermore, the high ligand-abstraction ability of MAO for a zirconocene complex is evaluated by the allylzirconation of internal alkyne, where MBO was found to be more satisfactory as cocatalyst than (Me2Al)(2)O and Me3Al in terms of reactivity.
