Novel Aromatic Trifluoromethylating Reagent

Trifluoromethylated aromatic compounds are important intermediates for the synthesis of pharmaceuticals, agrochemicals, and polymer materials, and thus, a number of trifluoromethylating reagents have been developed so far. (Trifluoromethyl)tris(triphenylphosphine)copper(I) (1), reported by Komiya¹⁾ and Grushin²⁾ et al., is an air-stable trifluoromethylating reagent with ease of handling, and the reagent has been reported to trifluoromethylate iodoarenes in the presence of tBu-bpy.
