-
Paragraph 0015-0017; 0020, (2022/01/07)
The invention relates to the technical field of fine chemical engineering, and discloses a method for preparing 2-alkylthiobenzonitrile, the method specifically comprises the following steps: taking 2-alkylthiobenzonamide as a raw material and sodium iodide, acetic acid and 1-chloromethyl-4-fluoro-1, 4-diazabicyclo [2.2. 2] octane bis (tetrafluoroborate) [Selectfluor] as additives, reacting in acetonitrile at 120 DEG C for 24 hours, and obtaining the target product 2-alkyl thiobenzonitrile. The method is easy and convenient to operate, reagents and raw materials are easy to obtain, phosphorus oxychloride which is high in toxicity and not easy to store does not need to be used as a dehydrating agent, 2-alkylthiobenzonitrile is efficiently synthesized in one step, and potential application value is achieved.
