  摘要：

  Me2NC2H4C5Me4Li reacts with Cr(THF)(3)Cl-3 to give (eta(1):eta(5)-Me2NC2H4C5Me4) CrCl2, in which the complexation of the N-donor atom to the metal atom has been confirmed by X-ray crystallography. A series of related compounds, e.g. (eta(1):eta(5)-cyclo-C4H8NSiMe2OSiMe2C5H4)-CrCl2 has been prepared by varying the substituents on the organic ligand. Further reaction with organomagnesium reagents leads to formation of the corresponding dialkyl-Cr complexes. Related species have been prepared containing imine-, alkoxy-, and alkylthiosubstituted cyclopentadienyl groups as well as the C-donor ligand tetramethylimidazol-2-ylidene. Treatment of these compounds with methylalumoxane (MAO) leads to the formation of highly active catalysts for the oligomerization, polymerization, and copolymerization of ethylene.

• Synthesis and Structures of (Dialkylamino)ethylcyclopentadienyl Derivatives of Zinc

  Lithium salts of (dialkylamino)ethylcyclopentadienyl react with either ZnCl2 or Zn(OAc)(2) to afford dimeric derivatives containing bridging chlorides or acetates, respectively. X-ray structural determinations of three such derivatives show that the cyclopentadienyl ligands are bound to the zinc centers in an eta (1) fashion and via their amine groups, thereby leading to a stable six-membered metallacycle.

  Reduction of the (eta(1),eta(5)-R2NC2H4C5Me4)CoCl complexes (R=Me, R-2=cyclo-C4H8), prepared by treating CoCl2 with 2-dimethylaminoethyl- or 2-pyrrolidinylethyl-tetramethylcyclopentadienyl-lithium with active-Mg in the presence of ethylene or dienes leads to the formation of (eta(5)-R2NC2H4C5Me4)(CH2:CH2)(2)Co(I) or (eta(5)-R2NC2H4C5Me4)(diene)Co(I) complexes. These react with ethereal HBF, with protonation of the amine followed, in the case of the diene complexes, by transfer of the proton to the diene to give (eta(1),eta(5)-R2NC2H4C5Me4)(eta(3)-allyl)Co(III)-salts.
