title: A Titanacycle-to-Carbocycle Relay Leading to an Expedient Synthesis of Cyclopentadienols.
abstract: 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.
