Synthesis of a titanium ethylene complex via C-H-activation and alternative access to Cp2Ti(eta(2)-Me3SiC2SiMe3)

摘要

The synthesis of the novel room temperature stable titanacyclopropane derivative Cp*Ti(eta(2)-C2H4)(eta(5)-C(5)H(4)AdH) (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(eta(2)-Me3SiC2SiMe3)(eta(5)-C(5)H(4)AdH) (4). Given these results, a novel one-pot procedure toward Cp2Ti(eta(2)-Me3SiC2SiMe3) was subsequently developed.
