Grubbs ring closing metathesis mechanism

Grubbs ring closing metathesis mechanism, Mechanism of ring closing metathesis the key intermediate is a metallacyclobutane, which can undergo cycloreversion either towards products or back to starting materials when the olefins of the substrate are terminal, the driving force for rcm is the removal of ethene from the reaction mixture.
