Spiridonov, Kirill A.; Kozinenko, Vitaly P.; Nikovsky, Igor A.; Pavlov, Alexander A.; Vol′khina, Tatyana N.; Nelyubina, Yulia V.; Kiryutin, Alexey S.; Yurkovskaya, Alexandra V.; Polezhaev, Alexander A.; Novikov, Valentin V.; Ivanov, Konstantin L. published an article in Mendeleev Communications. The title of the article was 《Phosphite-containing iridium polarization transfer catalysts for NMR signal amplification by reversible exchange》.Application In Synthesis of 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride The author mentioned the following in the article:
Two new iridium complexes with an N-heterocyclic carbine and phosphite ligands have been synthesized and characterized. Bubbling of parahydrogen through their solutions resulted in the formation of several hydride complexes. In the presence of pyridine, this process is accompanied by transfer of spin order from the mol. hydrogen to pyridine mols. undergoing dynamic exchange between free and complex-bound states. In the experiment, the researchers used many compounds, for example, 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0Application In Synthesis of 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride)
1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0) has been employed in an efficient, one-pot synthesis of N-heterocyclic carbene-allylpalladium complexes.Application In Synthesis of 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chlorideIn addition, it can efficiently catalyze the Suzuki-Miyaura coupling of aryl chlorides with aryl boronic acids.
