A new concept for immobilising Grubbs III catalyst by direct coordination of ruthenium to polyvinyl pyridine (PVP) is presented. PVP was prepared by precipitation polymerisation, which led to small bead sizes (0.2-2 m) and large surface areas. Compared to commercial resins, this phase showed ...

Furthermore, the NHC-based catalyst promotes olefin coordination and stabilizes the metallacycle intermediate, accelerating the overall activity [42]. Costabile and Cavallo [43] investigated the origin of enantioselectivity in the asymmetric Ru-catalyzed metathesis. Benitez, Tkatchouk and Goddard III [...
The ligands of the Grubbs catalyst are omitted from the mechanism for clarity, and the ruthenium atom has been replaced with a generic transition metal, M. The catalytic cycle for the Grubbs reaction with two terminal alkenes generates ethene in each catalytic cycle. Ethene escapes as a gas, ...
Firstly, the effects of three commonly used olefin metathesis catalysts on the system were evaluated, and Grubbs I was selected as the best catalyst. The conversion rate of methyl oleate and the yield of 1-decene and methyl 9-decenoate were taken as evaluation indexes to explore the process ...
