Tandem addition of the two carbon–titanium bonds of a titanacyclopentadiene to the ester group of the same molecule affords carbocycles (shown schematically): The metal portion of the metallacycle has been replaced with a carbon fragment. Depending on the starting diyne, mono‐, bi‐, or tricyclic compounds can be obtained.
