Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 1840-97-7, name is 2,4-Dibromo-1-(trifluoromethoxy)benzene, A new synthetic method of this compound is introduced below., Product Details of 1840-97-7
Add 1008 g of 2,4-dibromotrifluoromethoxybenzene, 5200 mL of DMF to the reaction vessel, and control the temperature to 150 C.Slowly add 774 g of cuprous cyanide solids with stirring.During the addition, the temperature should not exceed 155 C. After the addition, the reaction is stirred and the GC is traced until the reaction is over.After the reaction is completed, it is cooled, and the reaction product is poured into water to analyzeSolid, suction filtration,Extraction with 1,2-dichloroethane, followed by suction filtration, liquid separation, rotary evaporation, drying,Obtained a white powdery solid2,4-dicyanotrifluoromethoxybenzene 326 g,The yield was 49%.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
