| titleOfInvention | Process for preparing a trifluoromethylbenzene derivative |
| abstract | A process for preparing a trifluoromethylbenzonitrile derivative of the formula: <IMAGE> (I) wherein X is hydrogen, lower alkyl, halogenated lower alkyl, lower alkoxy, nitro, hydroxyl, amino, cyano, carboxyl or sulfon which comprises reacting trifluoromethylhalogenobenzene of the formula: <IMAGE> (II) wherein X is as defined above, and Y is halogen with copper (I) cyanide in a solvent selected from the group consisting of hexamethylphosphoric triamide, N-methylpyrrolidone and a mixture thereof in the presence of a catalyst selected from the group consisting of (A) bromine, (B) iodine, (C) a combination of bromine or iodine and metallic copper and (D) copper (II) bromide, by which process the compound (I) is prepared in a good yield, and by-products are produced in a lower yield than the conventional processes. |
