Description

This lecture explores the importance of computational chemistry in understanding and improving the Olefin Metathesis reaction. It covers the challenges faced in experimental chemistry due to the complexity of species involved. The presentation delves into the electronic structure, solvation, and dynamics of the reaction, emphasizing the role of theory and simulation in predicting and optimizing outcomes. The lecture also highlights the significant contributions of Yves Chauvin, Robert H. Grubbs, and Richard R. Schrock, who were awarded the 2005 Nobel Prize in Chemistry for their work on Olefin Metathesis.

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. Because of the relative simplicity of olefin metathesis, it often creates fewer undesired by-products and hazardous wastes than alternative organic reactions. For their elucidation of the reaction mechanism and their discovery of a variety of highly active catalysts, Yves Chauvin, Robert H. Grubbs, and Richard R.

Nobel Prize

The Nobel Prizes (noʊˈbɛl ; Nobelpriset nʊˈbɛ̂lːˌpriːsɛt; Nobelprisen nʊˈbɛ̀lːˌpriːsn̩) are five separate prizes that, according to Alfred Nobel's will of 1895, are awarded to "those who, during the preceding year, have conferred the greatest benefit to humankind." Alfred Nobel was a Swedish chemist, engineer, and industrialist most famously known for the invention of dynamite. He died in 1896. In his will, he bequeathed all of his "remaining realisable assets" to be used to establish five prizes which became known as "Nobel Prizes.

Grubbs catalyst

Grubbs catalysts are a series of transition metal carbene complexes used as catalysts for olefin metathesis. They are named after Robert H. Grubbs, the chemist who supervised their synthesis. Several generations of the catalyst have also been developed. Grubbs catalysts tolerate many functional groups in the alkene substrates, are air-tolerant, and are compatible with a wide range of solvents. For these reasons, Grubbs catalysts have become popular in synthetic organic chemistry. Grubbs, together with Richard R.

Shell higher olefin process

The Shell higher olefin process (SHOP) is a chemical process for the production of linear alpha olefins via ethylene oligomerization and olefin metathesis invented and exploited by Royal Dutch Shell. The olefin products are converted to fatty aldehydes and then to fatty alcohols, which are precursors plasticizers and detergents. The annual global production of olefines through this method is over one million tonnes. The process was discovered by chemists at Shell Development Emeryville in 1968.

Transition metal carbene complex

A transition metal carbene complex is an organometallic compound featuring a divalent organic ligand. The divalent organic ligand coordinated to the metal center is called a carbene. Carbene complexes for almost all transition metals have been reported. Many methods for synthesizing them and reactions utilizing them have been reported. The term carbene ligand is a formalism since many are not derived from carbenes and almost none exhibit the reactivity characteristic of carbenes.
