About bob robert h grubbs is for his contributions to the field of olefin metathesis water-soluble olefin metathesis catalyst based on an n-heterocyclic. A range of water-immiscible commercially available grubbs-type precatalysts can be used in ring-closing olefin metathesis reaction in high yields the synthetic transformation is possible in pure water under ambient conditions. A novel water-soluble ruthenium olefin metathesis catalyst supported by a poly(ethylene glycol) conjugated saturated 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene ligand is reported. There is a very limited number of water-soluble olefin metathesis catalysts known to date while many of them are not very efficient and active in water, most of them are extremely cumbersome to make and hence way too expensive on top of it. Olefin metathesis allows the exchange of substituents between different olefins - a transalkylidenation this reaction was first used in petroleum reformation for.
