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.
Olefin Metathesis allows the exchange of substituents between different olefins - a transalkylidenation. This reaction was first used in petroleum reformation for the synthesis of higher olefins (Shell higher olefin process - SHOP), with nickel catalysts under high pressure and high temperatures.
Grubbs’ catalyst is a transition metal carbene complex and there are two generations of the catalysts. 103 In contrast to other olefin metathesis catalysts, Grubbs’ catalysts tolerate other functional groups in the alkene and are compatible with a wide range of solvents. 103 For these reasons, Grubbs’ catalysts are extraordinarily versatile.
New generation catalyst with increased activity for olefin metathesis reactions; it gives excellent yields even in cases where the classic Grubbs catalyst fails
Professor Robert (Bob) Howard Grubbs’ main interests in organometallic chemistry and synthetic chemistry are catalysts, notably Grubbs’ catalyst for olefin metathesis and ring-opening metathesis polymerization with cyclic olefins such as norbornene. He also contributed to the development of so-called ‘living polymerization’. Read more.
The Grubbs catalyst is an organoruthenium complex. The π bond between carbon and ruthenium is at the center where the catalytic reaction occurs. Americans Robert H. Grubbs and Richard R. Schrock, and Frenchman Yves Chauvin shared the 2005 Nobel Prize in Chemistry for this reaction; a synthetic and mechanistic tour de force.
Jan 6, 2022 · Different organic reactions such as alkylation, arylation, isomerization and olefin metathesis are efficiently carried out in the presence of these catalysts within short reaction time. In 1992, Robert H. Grubbs first time introduced ruthenium-based catalyst, known as Grubbs first-generation catalyst (G-1) to carry out olefin metathesis ...
