limitations of the reaction between cyclopropylcarbene-chromium complexes and alkynes have been examined. A variety of cyclopropylcarbene complexes and alkynes have been employed in these studies. The reaction appears to be general for most simple alkynes, producing cyclopentenones. A mechanism has been proposed involving metallacyclobutene formation, electrocyclic ringopening, electrocyclic ring closure, CO
