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. 85068-32-2, name is 2-(3,5-Bis(trifluoromethyl)phenyl)acetonitrile, A new synthetic method of this compound is introduced below., Quality Control of 2-(3,5-Bis(trifluoromethyl)phenyl)acetonitrile
[0156] 0.46 g (1.33 mmol) of the Nile-red compound derivative, 0.50 g (1.99 mmol) of 3,5-bis(trifluoromethyl)phenylacetonitrile, and 50 ml of acetic anhydride were placed in a 100 ml pear-shaped flask. The solution in the pear-shaped flask was heated in a silicone oil bath to 135 C. and allowed to react for 2 hours. Acetic anhydride was distilled off with an evaporator and the residue was dissolved in chloroform. This chloroform solution was washed with a 5% aqueous solution of sodium hydroxide and then with water. After the addition of sodium sulfate, the solution was allowed to stand for 30 minutes to be dried. The dried solution was concentrated with an evaporator. The obtained solid was purified by a column chromatography that used silica gel and benzene. 14 mg of violaceous solid was obtained. The melting point of the violaceous solid was 183-185 C. An NMR chart of this product is shown in FIG. 11. The results of elemental analysis of this violaceous product are as follows. Based on these results, the obtained product was identified as the Nile Red luminescent compound represented by formula (22). [0157] The results of elemental analysis [0158] Found values: C: 67.02, H: 4.77, N: 5.13 [0159] Calculated values: C: 66.90, H: 4.71, N: 5.03
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.
