Some common heterocyclic compound, 7189-69-7, name is 1,1′-Sulfonyldiimidazole, molecular formula is C6H6N4O2S, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. SDS of cas: 7189-69-7
N,N? – sulfuryldiimidazole (5.00 g, 25.2 mmol, 1.0 eq) was then suspended in 50 mL of anhydrous dichloromethane at 0C under N2. Methyltrifluoromethanesulfonate (2.56 mL, 22.7 mmol, 0.9 eq) was added dropwise over 15 minutes at 0C. The reaction stirred at 0C for 2 hours. The solvent was decanted off and 3-(imidazole-1-sulfonyl)-1-methyl-3H-imidazol-1-ium triflate was isolated as a white solid was washed three times each with 50 mL of cold dichloromethane and dried under high vacuum for 10 minutes and immediately used in the next reaction.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 7189-69-7, its application will become more common.
