Abstract

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.
