The advances in this area have lead to the reaction becoming commonplace in the chemical industry especially in the development of pharmaceuticals and new plastic materials.

Olefin Metathesis by Group VI (Mo, W) Metal Compounds, Alkenes, Reza Davarnejad and Baharak Sajjadi, Intech Open, DOI: 10.5772/intechopen.69320.
His research interests are homogeneous catalysis by transition metals and Lewis acids; olefin metathesis and ROMP of cycloolefins; bioactive organometallic compounds; and mechanisms and stereochemistry of reactions in organic and polymer chemistry.

Working separately the three Nobel Laureates, Yves Chauvin, Richard Schrock and Robert Grubbs have optimised the metatheses reaction over the years by developing cleaner, more efficient catalysts.
Together their work means that as well as being a way of producing new molecules, metathesis reactions are faster, produce less waste which in turn is excellent for the environment, and they also meant that these types of reactions are far simpler to carry out as extreme conditions such as high temperatures are not required.Available from: Frédéric Lefebvre, Yassine Bouhoute, Kai C.Szeto, Nicolas Merle, Aimery de Mallmann, Régis Gauvin and Mostafa Taoufik (December 20th 2017).In metathesis double bonds between carbon atoms in organic substances are broken and made and subsequently atoms are moved to new positions within a molecule leading to the creation of a new organic substance.This movement is helped by a molecule which is known as a catalyst.Her interests are in stable organic free radicals – syntheses and applications as spin probes, olefin metathesis, Ru catalysis, transition metal complexes with free radical ligands and their magnetic and catalytic properties, azasugars and prostaglandin-related drugs.

In addition to alkene metathesis and ROMP reactions, involving eight electrons (8e (alkyne metathesis). Truett and others, the alkene metathesis reaction (a term coined by Calderon) and the related ring-opening metathesis polymerisation (ROMP) were developed in the following decades by many scientists, each bringing remarkable contributions to this productive area of organic synthesis and catalysis, see Figure (8(a)-8(c)).By awarding the 2005 Nobel Prize for Chemistry to Chauvin, Grubbs and Schrock, the outstanding contribution of metathesis for the progress of human society is being rightfully recognised.Valerian Dragutan is a Senior Researcher at the Institute of Organic Chemistry of the Romanian Academy (Splaiul Independentei 202 B, PO Box 35-108, 060023 Bucharest, Romania; E-mail: [email protected]).
