The general procedure for the synthesis of 2,4-bis(trifluoromethyl)aniline from 1-(trifluoromethyl)-1,2-phenyliodonyl-3(1H)-one and p-trifluoromethylaniline is as follows: in this embodiment, p-trifluoromethylaniline is used as the aromatic amine, and the rest of the reaction and post-treatment steps are the same as in embodiment 28. The specific reaction conditions were as follows: 1-(trifluoromethyl)-1,2-phenyliodono-3(1H)-one (0.5 mmol, 1.0 eq.), p-trifluoromethylaniline (1.5 mmol, 3.0 eq.), nickel hydroxide (10 μmol), and potassium carbonate (1.5 mmol, 3.0 eq.) were dissolved in DMSO (2 mL), and the reaction was carried out for 2 hr at 35 °C. After the reaction was completed, post-treatment was carried out according to the method in Example 1.
