Method of preparation of trifluoromethyl copper and trifluoromethyl aromatics

The process of direct synthesis of trifluoromethyl copper and trifluoromethyl aromatics, both intermediate reagents useful in direct synthesis of certain perfluoroalkyl compounds. The process involves a direct reaction between on the one hand an aromatic halide and a difluorodihalomethane and on the other hand copper and a difluorodihalomethane.
