Paragraph 0024-0065, (2021/10/27)
The invention discloses a synthesis method of 1-(2,4,6-triisopropyl phenyl sulfonyl) imidazole, and relates to the technical field of electrolyte additives. ,The synthesis method of the 1-(2,4,6-triisopropyl phenyl sulfonyl) imidazole comprises the following synthesis steps: step 1, adding imidazole, triethylamine and an organic solvent A into a reaction container provided with a stirrer and a thermometer at a temperature of 0-50 DEG C, starting stirring after the addition is finished to obtain a mixed solution B, dropwise adding a mixed solution C containing 2,4,6-triisopropyl benzene sulfonyl chloride into the mixed solution B and performing reaction for 2-6 hours after dropwise adding to obtain a reaction solution D. According to the present invention, with the improvement of the synthesis method, the yield of the 1-(2,4,6-triisopropyl phenyl sulfonyl) imidazole can be effectively improved, and the purity of the 1-(2,4,6-triisopropyl phenyl sulfonyl) imidazole can be improved so as to reduce the cost of the production and the subsequent application of the 1-(2,4,6-triisopropyl phenyl sulfonyl) imidazole.

The synthetic route phosphorus and sulfonyl-substituted N-imidazoles (triazoles) has been elaborated based on the method proposed by Birkofer et al.The appropriate compounds are obtained in high yield and of analytical purity by the action of N-trimethylsilyl imidazole (triazole) on the corresponding acid chlorides.
