A strong metal‐ligand π‐back bonding is the reason for the trans ‐arrangement of carbene‐ and olefin‐ligand in the complex 1 , for which an X‐ray structure analysis is available. Because of the ligand arrangement, a cyclization to the metallacyclobutane, an important intermediate in olefin metathesis, is impossible.
