Abstract:
Two novel ansa-zirconocenes containing SiMe2 bridge in non-conventional 4-position of 5-methoxy-6-tert-butylindenyl fragment have been synthesized, using TMS-protected substituted bromoindanol as a key starting compound. The structure of rac-dichloro- zirconium μ-4,4’-dimethylsilylene-bis(η5-6-tert-butyl-5-methoxy-2-methylinden-1-ide) was established by X-ray diffraction.
