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.
