<I>N</I>-Trifluoromethyl-<I>N</I>-nitrosotrifluoromethanesulfonamide (TNS-Tf) has been developed as a unique and effective trifluoromethylating agent which has two reactive CF<SUB>3</SUB> radicals in a molecule. It was found that TNS-Tf served as a useful reagent for trifluoromethylation of activated aromatics, mercaptans, disulfides, and a uridine dervative photochemically or thermally. It was also found that TNS-Tf reacted with activated copper suspended in a polar solvent at room temperature to give CF<SUB>3</SUB>-Cu complex which could convert aryliodides to CF<SUB>3</SUB>-aromatics in good yields.
