Olefin metathesis — or transalkylidenation is an organic reaction that entails redistribution of alkylene fragments by the scission of carbon carbon double bonds in olefins (alkenes).[1] Its advantages include the creation of fewer sideproducts and hazardous wastes … Wikipedia
Ring opening metathesis polymerisation — Ring opening metathesis polymerization (ROMP) is a type of olefin metathesis polymerization that produces industrially important products. The driving force of the reaction is relief of ring strain in cyclic olefins (e.g. norbornene or… … Wikipedia

Enyne metathesis — An Enyne metathesis is an organic reaction taking place between an alkyne and an alkene with a metal carbene catalyst forming a butadiene. This reaction is a variation of olefin metathesis. [ Enyne Metathesis (Enyne Bond Reorganization) Diver, S … Wikipedia
Ring-closing metathesis — or RCM is a variation on olefin metathesis that allows the closing of previously hard to make rings (7 8 member rings in particular). RCM is simply an intramolecular olefin metathesis with a Grubbs catalyst, yielding the cycloalkene and a… … Wikipedia
Ziegler–Natta catalyst — A Ziegler–Natta catalyst is a catalyst used in the synthesis of polymers of 1 alkenes (α olefins). Three types of Ziegler–Natta catalysts are currently employed: Solid and supported catalysts based on titanium compounds. They are used in… … Wikipedia
Concurrent tandem catalysis — (CTC) is a technique in chemistry which uses multiple catalysts on a single molecule in a one pot vessel to produce a product otherwise not accessible by a single catalyst. (see one pot synthesis) The scheme below illustrates this process.… … Wikipedia
