These Schrock carbenes led to more viable molybdenum complexes for this operation which worked under less exacting conditions, which inspired the ruthenium catalyst systems popularized by Grubbs.
Research at Columbia University by Thomas Katz with tungsten systems was key to discovering the role of metal carbenes in initiating this reaction, and was later followed up by the development of tantalum and tungsten carbene systems with high-metal oxidation states, distinct from the low-oxidation Fischer carbenes created before.

For ten points, name this reaction that involves exchanging of carbon- carbon double bonds between alkenes.
