332-25-2, 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. 332-25-2, name is 4-(Trifluoromethoxy)benzonitrile, A new synthetic method of this compound is introduced below.
Step A: Anhydrous CeCl3 (0.84 g, 3.4 mmol) was stirred in dry THF (10 mL), at room temperature, under a N2 atmosphere for 2 h. Then, the solution was cooled at -78 ¡ãC, followed by dropwise addition of MeLi (2.2 mL, 3.4 mmol, 1.6 M), and allowed to stir for 30 min at -78 ¡ãC. Then, a solution of 4-methoxybenzonitrile (0.15 g, 1.1 mmol) in dry THF (5 mL) was added dropwise to the above solution. The crude reaction was stirred at room temperature overnight, quenched by adding 1.5 mL of concentrated NH4OH, and allowed to stir for 1 h at room temperature. The organic layer was filtered, dried over anhydrous Na2SO4, and concentrated in vacuo. The crude product was used for next reaction without further purification.
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.
