Biography & contributions

Richard Royce Schrock an American chemist, Nobel laureate born on January, 04, 1945. Schrock is recognized for his contributions to the olefin metathesis reaction used in organic chemistry.

Schrock was the winner of many notable awards and medals like ACS Award in the year of 1985, Harrison Howe Award of the Rochester ACS section in the year of 1990, Alexander von Humboldt Award in the year of 1995, ACS Award in Inorganic Chemistry in the year of 1996, Bailar Medal from the University of Illinois in the year of 1998, ACS Cope Scholar Award in the year of 2001, Nobel Prize in Chemistry, with Robert H. Grubbs and Yves Chauvin, for his work in the area of olefin metathesis in the year of 2005, August Wilhelm von Hofmann Medal from the German Chemical Society in the year of 2005, F. Albert Cotton Award in Synthetic Inorganic Chemistry and Theodore Richards Medal from the Northeast ACS section in the year of 2006, Basolo Medal in the year of 2007.

He worked in the area of olefin metathesis, an organic synthesis technique. Schrock elucidated the structure and mechanism of so-called 'black box' olefin metathesis catalysts and created class of compounds known as 'Schrock Carbenes'. He demonstrated about metallacyclobutanes are the key intermediate in olefin metathesis.

Facts about olefin metathesis

Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds. Olefin metathesis is a popular and useful reaction. In the presence of certain transition-metal compounds like metal carbenes, olefins exchange the groups around the double bonds, resulting in several outcomes: straight swapping of groups between two acyclic olefins, closure of large rings, formation of dienes from cyclic and acyclic olefins polymerization of cyclic olefins, and polymerization of acyclic dienes.

The power of olefin metathesis is that it transforms the carbon-carbon double bond, a functional group that is un-reactive toward many reagents that react with many other functional groups. With certain catalysts, new carbon-carbon double bonds are formed at or near room temperature even in aqueous media from starting materials that bear a variety of functional groups. Use of olefin metathesis in organic synthesis has been directly correlated to improvements in metal-carbene catalysts.
