ring formation reaction step
ring-closing metathesis
A joining reaction in which two carbon-carbon double bonds in the same molecule are redistributed to give a cycloalkene. It is typically catalysed by a metal carbenoid, and proceeds via two four-membered intermediates (metallacyclobutanes). The reaction is driven by release of a low-MW alkene.
