✦ Synopsis

A series of ester-carbene complexes was synthesized. These complexes were found to be highly active for the metathesis of ole®nic substrates, including acrylates and trisubstituted ole®ns. In addition, the ester-carbene moiety is thermodynamically high in energy. As a result, these complexes react to ring-open cyclohexene by metathesis to alleviate the thermodynamic strain of the ester-carbene ligand.
