Introduction of a new synthetic route about 368-77-4

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.

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. 368-77-4, name is 3-(Trifluoromethyl)benzonitrile, A new synthetic method of this compound is introduced below., Quality Control of 3-(Trifluoromethyl)benzonitrile

General procedure: In a glove box, a flame-dried GLC vial equipped with a magnetic stir bar is charged with[3a]+[BArF4]- (1.0 mol%) and Me2PhSiH (2a) (2.1 or 5.0 equiv). The indicated nitrile is added eitherin the glove box (for solid starting materials) or by micro syringe outside the glove box, and theresulting reaction mixture is maintained at room temperature for the indicated time. The reaction isquenched by the addition of a mixture of cyclohexane and tert-butyl methyl ether (90:10) containing4% Et3N (0.5 mL), and the resulting solution is filtered through a pad of Celite coated by a smalllayer of silica gel with a solution of cyclohexane and tert-butyl methyl ether (90:10) containing 4%Et3N (3-4 mL) as eluent. Solvents are removed under reduced pressure, and the residue isdissolved in Et2O (1 mL) followed by addition of HCl (2M in Et2O, 1.0 mL, 2.0 mmol, 10 equiv). Theresulting suspension is stirred for 1 h and filtered, affording the amines as hydrochloride salts aswhite to yellow solids.
