Questions And Answer | Back Directory | [Description]
2-Chloro-1,3-dimethylimidazolidinium chloride has various applications including being used as activating agent in total synthesis of macroviracin A, cycloviracin B1 and cyclic silanes; used as reagent for synthesis of tagged glucose as an intermediate in the synthesis of branched oligosaccharides; used as fluorescent chemosensors; 1,2-Diamines as inhibitors of co-activator associated arginine methyltransferase 1; used as allosteric glucokinase activators; as reactant for synthesis of organic azides from primary amines and for aza-Henry reactions1. It can act as a powerful dehydrating agent, replacing DCC under nearly neutral conditions, and has application for the construction of heterocycles2. Moreover, it can be used for one-pot synthesis of 2-aminobenzimidazoles3. It is also applicable to chlorination, oxidation, reduction, and rearrangement under nearly neutral conditions4.

General procedure for the synthesis of 2-chloro-1,3-dimethylimidazolium chloride from 1,3-dimethyl-2-imidazolidinone: In a 1000 ml three-necked reaction flask, 1,3-dimethyl-2-imidazolidinone (34.2 g, 0.3 mol) and carbon tetrachloride (400 ml) were added. A carbon tetrachloride solution of solid phosgene (containing 30 g of solid phosgene, 0.1 mole, dissolved in 100 mL of carbon tetrachloride) was added slowly and dropwise. The temperature of the reaction mixture was controlled below 5°C with vigorous stirring for 0.5 hours. Subsequently, the reaction mixture was brought to room temperature and the reaction was continued for 1 hour. Next, it was heated to 50°C and kept at this temperature for 4 hours. Upon completion of the reaction, the mixture was cooled to room temperature, filtered, and washed with a small amount of carbon tetrachloride to afford 49 g of a pure white crystalline product, 2-chloro-1,3-dimethylimidazolium chloride, in 96.6% yield. | [References]
