n Bu 4 N + [Ag I (CF 3 ) 2 ] - : Trifluoromethylated Argentate Derived from Fluoroform and Its Reaction with (Hetero)Aryl Diazonium Salts.

The preparation of a well-defined trifluoromethylated argentate n Bu 4 N + [Ag(CF 3 ) 2 ] - 1 from fluoroform was described. The complex was stable in the solid state and in solution under an inert atmosphere. Treatment of a variety of (hetero)aryl diazonium tetrafluoroborates with n Bu 4 N + [Ag(CF 3 ) 2 ] - 1 generated trifluoromethylated (hetero)arenes in good to excellent yields. Preliminary experiments were conducted, and a reasonable mechanism of the reaction was proposed.
