In a patnet, once mentioned the new application about 301224-40-8, Recommanded Product: (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride
An olefin metathesis catalyst (8) bearing a hemilabile N-heterocyclic carbene (NHC) ligand with four methoxyethoxy arms was synthesized and analyzed by X-ray crystallography and NMR spectroscopy. The solid-state structure of the catalyst reveals that one of the aromatic rings is rotated toward the plane of the NHC heterocycle, which enables one ortho-O?Ru coordination. Ring-closing metathesis (RCM) activity was tested at low catalyst loadings. Catalyst 8 was found to display a significant rate enhancement relative to the commercial catalyst 3 but offered no improvement in turnover numbers (TON). The solid-state structure of the catalyst’s major degradation product (9) in the presence of 1-hexene reveals a dinuclear compound containing a bridging methylidene (Ru-CH2-Ru), indicating that the methoxyethoxy arms may not be strong enough to stabilize the (NHC)RuCl2(?CH2) catalyst resting state.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Product Details of 301224-40-8. In my other articles, you can also check out more blogs about 301224-40-8
