Independent of the molar ratio of the starting materials tylamido-dime
thylsilyl)cyclopentadienyl]zirconium, (t-C4H9N-SiMe2-C5H4)2Zr, is form
ed as a spiranoide zirconacyclus by reaction of ZrCl4 - 2THF with [t-C
4H9N-SiMe2-C5H4]Li2. The constitution was elucidated by means of H-1 a
nd C-13 NMR spectroscopy.
