With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.141556-45-8,1,3-Dimesityl-1H-imidazol-3-ium chloride,as a common compound, the synthetic route is as follows.
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).
141556-45-8 1,3-Dimesityl-1H-imidazol-3-ium chloride 2734211, achiral-catalyst compound, is more and more widely used in various.
