Paragraph 0034-0036; 0039; 0042; 0045, (2018/01/19)
The invention discloses a 2 - mercapto - 1 - alkyl imidazole synthesis method, which belongs to the technical field of organic synthesis. Imidazole and alkyl halide in the presence of an inorganic base sealing reaction the temperature of the 1 - alkyl imidazole, then dissolved in ether in the solvent, the low temperature by adding 1 - 1.1 equivalent BuLi, then adding 0.9 - 0.95 equivalent powder reflux reaction, after cooling add acetyl chloride to obtain 2 - acetyl thio - 1 - alkyl imidazole; the final 2 - acetyl thio - 1 - alkyl imidazole dissolved in alcohol solvent, adding a catalytic amount of hydrogen chloride or potassium carbonate deprotection, to obtain 2 - mercapto - 1 - alkyl imidazole. The raw material of the invention is cheap, and more friendly to the environment, the advantages of easy operation, the quality of the product in accordance with the electronic chemicals using standard.
