A common heterocyclic compound, the chiral-catalyst compound, name is 1,3-Dimesityl-1H-imidazol-3-ium chloride,cas is 141556-45-8, mainly used in chemical industry, its synthesis route is as follows.,141556-45-8
Prepared according a procedure of Mohr et al.21 To a soln of1,3-bis(2,4,6-trimethylphenyl)imidazolium chloride (175 mg,0.513 mmol) in CH2Cl2 (10 mL) was added HgO (108 mg,0.514 mmol) and Me4NCl (56.4 mg, 0.51 mmol). After stirring at r.t. for 15 h, the soln was passed through Celite, the solvent was removed in vacuo, and the residue was washed with H2O (2 ¡Á 10 mL) and Et2O (2 ¡Á 10 mL) to give 14 as a colorless solid; yield: 240 mg (82%); mp 270 C (dec); Rf = 0.09 (CH2Cl2-MeOH, 10:1).
As the rapid development of chemical substances, we look forward to future research findings about 141556-45-8
