Paragraph 0035-0036, (2016/10/24)
The invention discloses a method for preparing o-trifluoromethyl phenylamine and derivatives thereof. According to the method, phenylamine or a phenylamine derivative serving as raw material reacts with a trivalent iodine reagent compound 2 in a solution under the protection of argon or nitrogen and illumination condition in the presence of tri(2-phenylpyridine)-iridium [Ir(ppy)3] serving as a catalyst to produce o-trifluorophenylamine or derivatives thereof 3, wherein the trivalent iodine reagent compound 2 has a structure shown in the specification. The method is mild in reaction conditions, the amino does not need to be protected, and trifluoromethyl substituted phenylamine or phenylamine derivatives can be directly obtained.
