Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. 1739-84-0, formula is C5H8N2, Name is 1,2-Dimethyl-1H-imidazole. Their solubility in alcohol is lower than that in water and decreases with increasing molecular weight of the alcohols . Reference of 1739-84-0.
Kumar, Sunil;Singh, Sohan;Gadwal, Jitendra;Makar, Parvesh;Joshi, Hemant research published 《 Regioselective C-H arylation of imidazoles employing macrocyclic palladium(II) complex of organoselenium ligand》, the research content is summarized as follows. In this report, a new air stable bidentate selenium ligand was synthesized by the reaction of 1,8-bis(2-(chloromethyl)phenoxy)octane with sodium salt of phenylselenol. The reaction of this ligand with Pd(CH3CN)2Cl2 in acetonitrile under reflux conditions resulted in 19-membered ring macrocyclic palladium(II) complex. The structure of ligand precursors, ligand, and macrocyclic palladium(II) complex were authenticated by using 1H, 13C{1H} NMR spectroscopy and elemental anal. The obtained air and moisture stable, thermally robust macrocyclic palladium(II) complex was employed as catalyst for regioselective arylation of 1-methylimidazole and 1,2-dimethylimidazole with a variety of aryl bromides. The mild reaction conditions, exclusive C-5 regioselectivity, excellent yields (∼73-95%), low catalyst loading (1.5 mol%) and functional group tolerance are the advantages of this protocol. Homogeneous nature of catalysis process was confirmed with the help of mercury and triphenylphosphine poisoning tests. The catalyst can be recycled and reused with significant loss (22%) in efficiency.
1739-84-0, 1,2-Dimethylimidazole is used in the synthesis of 1,2-dimethyl-3-n-butylimidazoliumchloride and 1,2-dimethyl-3-n-propylimidazolium chloride. It also can be used in the synthesis of 1-(2-methoxyethyl)-2,3-dimethylimidazolium chloride and hexafluorophosphate salts.
1,2-Dimethylimidazole is a heterocyclic compound that contains nitrogen and carbon. It can be produced by the reaction between glyoxal and fatty acid in the presence of a base. 1,2-Dimethylimidazole has been shown to have biological properties such as an antioxidant effect. It is also used as a chemical intermediate for production of other chemicals such as 2-methylimidazole and 3-methylimidazole. 1,2-Dimethylimidazole has been shown to react with metal carbonyls to produce methylimines, which are useful intermediates in organic synthesis. The reaction mechanism involves hydrogen bonding and steric interactions between the imidazole ring and the metal carbonyl reactant., Reference of 1739-84-0
