In contrast to an orbital picture for an alkene, an orbital picture for an alkylidene pi bond suggests orbital symmetry that can easily interact with the LUMO on an alkene.
Alkane Metathesis Schrock
This reaction results in a four-membered ring, called a metallacyclobutane.
Olefin metathesis, or alkene metathesis, is an important process in petroleum refining and in the synthesis of important compounds such as pharmaceuticals.
The mechanism of olefin metathesis is related to pericyclic reactions like Diels Alder and [2 2] reactions.
There are other variations, including some designed for alkyne metathesis rather than alkene metathesis.
There is also a commercially-available Schrock-Hoveyda catalyst; that one is chiral, and can be used to carry out olefin metathesis enantioselectively.
