SYNTHESE UND DYNAMISCHES VERHALTEN VON EINIGEN PENTAMETHYLCYCLOPENTADIENYLSILANEN UND -GERMANEN

By reaction of pentamethylcyclopentadienyllithium (pcpLi) with the corresponding chloro-silanes and -germanes, the h1-pcp-silanes and -germanes I-IX are synthesized.Nucleophilic substitution reactions at the pcp-chlorogermane VII lead to the h1-pcp-germanes X-XIII.The activation parameters for the sigmatropic rearrangements in these compounds have been evaluated from the 1H DNMR data.They show little incluence of the remaining ligands at silicon or germanium on the speed of these dynamic processes.

Facile Reduction of Organometallic Halides with Bis(pentamethylcyclopentadienyl)ytterbium and the X-Ray Structure of (C5Me5)2YbCl(THF)

Reduction of (C5H5)2MCl2 (M=Ti, Zr) and TiCl4 with one equiv. of (C5Me5)2Yb(THF)2 gave rise to the formation of 2 and TiCl3(THF)3, respectively, together with (C5Me5)2YbCl(THF).The molecular structure of (C5Me5)2YbCl(THF) has been determined by the X-ray analysis.The reaction of (C5Me5)2Yb(THF)2 with Me3SiCl yielded a mixture composed of n and C5Me5(CH2)4OSiMe3.
