  摘要：

  Two new monoanionic tetradentate triamino-amide ligands, [(Me2NCH2CH2)(2)N-B-N(t-Bu)](-) (B = (CH2)(2), L-1; SiMe2, L-2) were prepared. Reaction of LIH with Y(CH2SiMe3)(3)(THF)(2) yielded (LY)-Y-1(CH2SiMe3)(2) (1), which was structurally characterized. Compound 1 decomposes at ambient temperature via metalation of one of the NMe2 methyl groups to give {[(CH2)MeN(CH2)(2)] [Me2N(CH2)(2)]N(CH2)(2)N(t-Bu)}Y(CH2SiMe3) (2). Attempts to prepare (LY)-Y-1(CH2SiMe3)(2) resulted in very rapid ligand metalation. Both 1 and 2 react with [PhNMe2H][B(C6F5)(4)] to generate the cation [(L-1)YCH2SiMe3](+). The combination of 1 and [Ph3C] [B(C6F5)(4)] is active in catalytic ethene polymerization, but with a short catalyst lifetime. The metalated complex 2 reacts with ethene and with pyridine by stoichiometric insertion into the Y-CH2N bond, and the latter product was structurally characterized. In (LY)-Y-1(X)(CH2SiMe3) complexes, the Y-amine distance trans to X is very sensitive to the nature of X, suggesting the presence of a trans influence.

  A cationic Group 3 or Lanthanide metal complex for coordination polymerization of olefins is disclosed. The precursor metal complex is stabilized by an anionic multidentate ancillary ligand and two monoanionic ligands. The ancillary ligand and the transition metal form a metallocycle having at least five primary atoms, counting any &pgr;-bound cyclopentadienyl group in the metallocycle as two primary atoms. Olefin polymerization is exemplified.
