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.
In organic chemistry, 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. [ 1 ] [ 2 ] Because of the relative simplicity of olefin metathesis, it often creates fewer undesired by-products and hazardous wastes than alternative ...
Grubbs's main research interests were in organometallic chemistry and synthetic chemistry, particularly the development of novel catalysts for olefin metathesis. In olefin metathesis, a catalyst is used to break the bonds of carbon molecules, which can then re-form to create chemical bonds in new ways, producing new compounds with unique ...

Frontal ring-opening metathesis polymerization (FROMP) is a variation of ROMP. It is a polymerization system that only reacts on a localized zone. [10] One example of this system is the FROMP of dicyclopentadiene with a Grubbs' catalyst initiated by heat. [11]
The Zhan catalysts were inspired by previous work in the olefin metathesis field. Robert H. Grubbs first reported the first and second generation of Ru catalysts in 1992, with good metathesis activity. However, the catalysts containing the tricyclohexylphospine ligand were unstable to air and water, and the catalytic activity is not good enough ...
