Dissolve 2-chloro-4-fluorobrobenzene into an appropriate amount of anhydrous organic solvent, such as tetrahydrofuran. Stir well to form a homogeneous liquid.
Take magnesium metal for a second time, clean its surface in an appropriate way, and remove its oxide layer. Carefully add clean magnesium chips to the above solution. During this process, the reaction temperature should be carefully controlled, usually maintained at a low temperature, such as between 0 ° C and 5 ° C, to prevent the reaction from being too dramatic. Magnesium gradually reacts with 2-chloro-4-fluorobromobenzene to form 2-chloro-4-fluorophenyl magnesium bromide, which is Grignard's reagent. Looking at the reaction phenomenon, the color of the solution may change, and there is a slight heat release.
After the Grignard's reagent is formed, slowly raise the temperature of the reaction system to room temperature to make the reaction more complete. Afterwards, carefully add the droplets of Grignard's reagent to a sulfur-containing reagent solution, such as an aqueous solution of sodium hydrosulfide. This step also needs to pay attention to the temperature, not too high, to avoid side reactions. Sodium hydrosulfide interacts with Grignard's reagent, and through a series of reactions, 2-chloro-4-fluorothiophenol is finally obtained.
After obtaining 2-chloro-4-fluorothiophenol, it can be reacted with alkali to obtain 2-chloro-4-fluorothiophenol salt. Take an appropriate amount of alkali, such as sodium hydroxide, dissolve it in water, and prepare a certain concentration of alkali solution. Add 2-chloro-4-fluorothiophenol slowly to this alkali solution, stir fully, and a neutralization reaction occurs between acid and base to generate 2-chloro-4-fluorothiophenol salt. After the
reaction is completed, the product can be separated from the reaction mixture according to common separation and purification methods, such as extraction, distillation, recrystallization, etc., to obtain pure 2-chloro-4-fluorothiophenol salt. During the whole process, it is extremely important to control the reaction conditions. Factors such as temperature, reagent dosage, and reaction time all affect the yield and purity of the product.
