1,3-Dimesityl-1H-imidazol-3-ium chloride(cas: 141556-45-8) is a ligand for arylation of aldehydes and for carbene catalyzed intermolecular arylation of C-H bonds. It is used as a phosphine-free ligand in various metal-catalyzed coupling reactions, often with advantageous results in difficult cases.Recommanded Product: 1,3-Dimesityl-1H-imidazol-3-ium chloride

The article was written by Shepelenko, Konstantin E.; Nikolaeva, Ksenia A.; Shevchenko, Maxim A.; Tkachenko, Yurii N.; Minyaev, Mikhail E.; Chernyshev, Victor M.. The article contains the following contents:

Ruthenium(II) complexes [(p-cymene)RuCl(3-R-Im-1-CH2CO2)] (1a-c, H2Im = 2-imidazolylidene; R = Me, Mes, Dipp), [(p-cymene)RuCl(3-R1-Im-1-CH2CONR2)] (2a-d; R1 = Me, Mes, Dipp; R2 = Dipp, tBu, Mes) with chelating N-heterocyclic carbene (NHC) ligands functionalized with carboxy and carboxamidato pendant groups, were prepared and examined as catalysts for ortho-C-H arylation of Ph groups in 2-phenylpyridine and 1-phenylpyrazole with aryl chlorides in water affording substituted 2-(m-terphenylyl)pyridines and 1-(m-terphenylyl)pyrazoles. Complexes with NHC-ligands containing a hemilabile coordinating N-carboxylatomethyl group enable fast and selective ortho-CH-diarylation in the absence of carboxylate-assisting additives. In the experimental materials used by the author, we found 1,3-Dimesityl-1H-imidazol-3-ium chloride(cas: 141556-45-8Recommanded Product: 1,3-Dimesityl-1H-imidazol-3-ium chloride)
