Synthesis of a titanium ethylene complex: Via C-H-activation and alternative access to Cp2Ti(η2-Me3SiC2SiMe3)
Fischer M., Vincent-Heldt L., Hillje M., Schmidtmann M., Beckhaus R.
The synthesis of the novel room temperature stable titanacyclopropane derivative Cp∗Ti(η2-C2H4)(η5-C5H4AdH) (2) in a one-step-two-transformation protocol and first insights into its reactivity are presented, including the synthesis of the corresponding bis(trimethylsilyl)acetylene complex Cp∗Ti(η2-Me3SiC2SiMe3)(η5-C5H4AdH) (4). Given these results, a novel one-pot procedure toward Cp2Ti(η2-Me3SiC2SiMe3) was subsequently developed.
