Alpha,beta-(C-C-C) agostic bonds in transition metal based olefin metathesis catalyses.
An alpha,beta-(C-C-C) agostic bond is found to provide the additional stabilization needed to make the formally 14-electron metallacyclobutane intermediate lower in energy than its 16-electron alkylidene analogue during olefin metathesis catalysis.
