  摘要：

  The dimer of lithium mu(2),eta(1)-N-[(N,N-Dimethylamino)dimethylsilyl]-2,6-diisopropylanilidate [1c, [LiN(2,6-(Pr2C6H3)-Pr-i)Si(CH3)(2)N(CH3)(2)](2) represented as (LiL)(2)] reacted with group 4 chlorides to form corresponding compounds, which were crystallized and confirmed by X-ray diffraction analysis as compounds of pseudotetrahedral ZrL2Cl2 (2) and chloro-bridged dinuclear tetrahedral compounds ZrLCl2(y-Cl)(2)Li center dot 2THF (3), ZrLCl2(mu-Cl)(2)Li center dot 2Et(2)O (4), HfLCl2(p-Cl)(2)Li center dot 2Et(2)O (5), and [ZrLCl2(mu-Cl)](2) (6). The catalytic behaviors of group 4 compounds were investigated in the presence of MAO as a cocatalyst. Compound 4 exhibited high activity for ethylene polymerization, while compounds 2 and 6 showed good activities for both ethylene polymerization and ethylene/ I -hexene copolymerization.
