Dykeman, Ryan R.; Yan, Ning; Scopelliti, Rosario; Dyson, Paul J. published an article on February 7 ,2011. The article was titled 《Enhanced rate of arene hydrogenation with imidazolium functionalized bipyridine stabilized rhodium nanoparticle catalysts》, and you may find the article in Inorganic Chemistry.Application In Synthesis of 4,4′-Bis(chloromethyl)-2,2′-bipyridine The information in the text is summarized as follows:
The imidazolium functionalized bipyridine compounds, {4,4′-bis[7-(2,3-dimethylimidazolium)heptyl]-2,2′-bipyridine}2+ ([BIHB]2+) and {4,4′-bis[(1,2-dimethylimidazolium)methyl]-2,2′-bipyridine}2+ ([BIMB]2+), were prepared and used as Rh nanoparticle stabilizers. The dispersed Rh nanoparticles were used as catalysts in the biphasic hydrogenation of various arene substrates. The catalytic activity was strongly influenced by the stabilizer employed and followed the trend [BIHB]2+ > bipy > [BIMB]2+. The steric and electronic characteristics of the imidazolium functionalized bipyridine ligands were assessed via the synthesis of rhenium carbonyl complexes, which facilitated the rationalization of the catalytic properties of the nanoparticles. The results came from multiple reactions, including the reaction of 4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4Application In Synthesis of 4,4′-Bis(chloromethyl)-2,2′-bipyridine)
4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. Application In Synthesis of 4,4′-Bis(chloromethyl)-2,2′-bipyridine Pyridine has a conjugated system of six π electrons that are delocalized over the ring.
