Bridge-functionalized bisimidazolium bromides as catalysts for the conversion of epoxides to cyclic carbonates with CO2 was written by Li, Yuanhui;Dominelli, Bruno;Reich, Robert M.;Liu, Boping;Kuhn, Fritz E.. And the article was included in Catalysis Communications in 2019.Recommanded Product: 1-Octyl-1H-imidazole This article mentions the following:
Six novel bridge-functionalized bisimidazolium bromides were synthesized and applied as catalysts for the cycloaddition of carbon dioxide and epoxides to give cyclic carbonates. Addnl., the influence of the hydrogen-bond donors, the N-wing-tip-substituents and the chain length of the connecting carbon bridges on the catalytic activity were studied. Catalyst bis[(trimethylphenyl)imidazoliumyl]methylpropanoic acid dibromide proved to be slightly more active than the reference catalyst bis(octylimidazoliumyl)propanol dibromide for the addition of carbon dioxide to various epoxides and could be analogously recycled from propylene carbonate for at least six times without distinct loss of activity. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Recommanded Product: 1-Octyl-1H-imidazole).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Recommanded Product: 1-Octyl-1H-imidazole
