摘要：
Constrained geometry complexes (CGCs) of titanium (IV) and zirconium (IV) containing isomeric cyclopentadienyls fused to thiophene fragment, i.e., 4,5-dimethylcyclopenta[b]thienyl and 5,6-dimethylcyclopenta[b]thienyl, have been prepared and unambiguously characterized. The molecular structure of the titanium complex [eta(5)-(5,6-dimethylcyclopenta[b]thienyl)SiMe2((NBu)-Bu-t)-eta(1)]TCl2 was established by X-ray crystal structure analysis. Preliminary studies showed that the studied CGCs/MAO are active olefin polymerization catalysts. (c) 2005 Elsevier B.V. All rights reserved.
