alkane metathesis schrock



Alkane metathesis is a class of chemical reaction in which an alkane is rearranged to give a longer or shorter alkane product. It is similar to olefin metathesis, except that olefin metathesis cleaves and recreates a carbon-carbon double bond, but alkane methathesis operates on a carbon-carbon single bond.
Alle drei Chemiker, Chauvin, Schrock und Grubbs erhielten im Jahr 2005 für ihre Erkenntnisse und die großen Fortschritte in der Entwicklung der Metathese den Nobelpreis für Chemie. Neben den Erfolgen in der Forschung suchte die Industrie nach weiteren Anwendungen für die Olefinmetathese. Ende der 1980 wurden
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. Schrock were
Alkane metathesis via tandem transfer dehydrogenation–olefin metathesis illustrated with the formation and metathesis of two molecules of 1-alkene. ... Numerous olefin metathesis catalysts are available (18–20); we examined the Schrock-type catalyst 3 (21, 22) after determining that the widely used Grubbs-type catalysts

Along these lines, the alkene metathesis reaction has been the topic of considerable interest for computational chemists. Computational studies have contributed to a better understanding of the metathesis reaction, either catalyzed by Schrock-type complexes, based on high-oxidation state group 6 and 7 metals [2–11],
