Efforts to develop alternatives to triflicanhydride (Tf2O) as a trifluoromethylation reagent continue due to its limitations, including volatility, corrosiveness, and moisture sensitivity. Described herein is the use of a trifluoromethylsulfonylpyridinium salt (TFSP), easily obtained by a one-step reaction of Tf2O with 4-dimethylaminopyridine, as a reagent for the trifluoromethylative difunctionalization
