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 [η5-(5,6-dimethylcyclopenta[b]thienyl)SiMe2(NtBu)-η1]TiCl2 was established by X-ray crystal structure
制备了钛(IV)和锆(IV)的稠密几何配合物(CGC),它们包含与噻吩片段融合的异构环戊二烯基,即4,5-二甲基环戊[ b ]噻吩基和5,6-二甲基环戊[ b ]噻吩基,并明确地表征。钛络合物的分子结构[η 5 - (5,6- dimethylcyclopenta [ b ]噻吩基)森达2(N吨丁基)-η 1 ]的TiCl 2,通过X射线晶体结构分析确定。初步研究表明,所研究的CGC / MAO为活性烯烃聚合催化剂。
