Abstract
[GRAPHICS] Benzocyclopropene and cyclopropa[b]naphthalene react with dichloro-bis(tric yclohexylphosphine)methylideneruthenium, incorporating the metallacarbene t o form unstable 3-ruthenacyclopentenes, which decompose to give o-xylylenes that can be trapped as Diels-Alder adducts by dimethyl acetylenedicarboxyl ate. In contrast, bis(eta (5)-cyclopentadienyl)methylidenetitanium forms mo derately stable 2- and 3-titanacyclopentene complexes.
