A novel intramolecular cyclisation of titanocene vinylidene complexes: formation of bicyclic titanacyclo-butanes and -butenes
Abstract
The Intramolecular addition of a titanocene vinylidene complex formed by dechlorodimethylalumination of a 1-dimethylalumino-1-bis(η5-cyclopentadienyl)chlorotitano-alkene to an unactivated alkene or alkyne affords bicyclic titanacyclobutanes or titanacyclobutenes.
