Аннотация:Tetrahydroindenes including spiro-cyclopentyl and -cyclohexyl fragments were successfully synthesized either via base-catalyzed cyclization of the respective gamma-diketone or via acid-catalyzed Nazarov cyclization of the corresponding divinylketones. These substituted cyclopentadienes were metallated with (BuLi)-Bu-n. The following reaction of the lithium salts with Cp*ZrCl3 gave three novel zirconocenes bearing spiro-cycloalkane fragments. One of these complexes, (eta(5)-5',6',7'-trihydrospiro[cyclohexane-1,4'-(2-methylindenyl)]) (eta(5)-pentamethyl-cyclopentadienyl)zirconium dichloride, has been characterized by X-ray crystal structure analysis.
