Adding a certain compound to certain chemical reactions, such as: 2338-75-2, name is 4-(Trifluoromethyl)phenylacetonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 2338-75-2, Application In Synthesis of 4-(Trifluoromethyl)phenylacetonitrile
INTERMEDIATE 1; Step A; A solution of 4-trifluoromethylphenylacetonitrile (10 g, 49 mmol) in a mixture of ethanol (100 mL) and ammonium hydroxide (20 mL of a 29.3% aqueous solution) was hydrogenated over Raney nickel (1 g) for 16 h. The catalyst was removed by filtration through celite and the filtrate evaporated to dryness. The neat residue was added in a dropwise manner to trifluoroacetic anhydride (25 mL, 180 mmol) cooled at 0 C. and the resulting mixture stirred at 0 C. for 30 minutes. The reaction mixture was poured onto ice (250 mL) and the resulting mixture stirred for 30 minutes after which the precipitate was removed by filtration and air dried to give the product as a white solid (13.4 g, 90%).
