  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.

Complex 4 reacts with 4.0 equiv of HSiEt3 per iridium to give the iridium(V) silyl trihydride derivative IrH3(η5-CpO)(SiEt3) (10), which in the presence of excess of HSiEt3 is transformed into IrH2(η5-CpO)(SiEt3)2 (11). Treatment at −40 °C of 4 with 2.0 equiv of HSiEt3 per iridium leads to a mixture of the hydride dichloro triethylsilyl complex IrH(η5-CpO)Cl2(SiEt3) (12)

  The course of the reactions between complex OsH2Cl2((PPr3)-Pr-i)(2) (1) and the functionalized cyclopentadienyllithium derivatives Li[C5H4(CH2)(2)E] (E = NMe2 (2), OMe (3)) strongly depenas on the solvent used. Thus, in the presence of donor solvents such as THF, the salts [OsH2eta(5)-C5H4(CH2)(2)E}((PPr3)-Pr-i)(2)][OsHCl2(CO)((PPr3)-Pr-i)(2)] (E = NMe2 [4][5], OMe [6][5]) with a carbonylated osmium anion are produced, while in hydrocarbon solvents the chloride salts [OsH2eta(5)-C5H4(CH2)(2)E}(PPr3)(2)]Cl (E NMe2 [4]Cl, OMe [6]Cl) are formed.
