Abstract

Thumbnail image of graphical abstract

The incorporation of a trifluoromethyl (CF3) group into organic compounds is of great importance in pharmaceutical, agricultural, and materials science. Trifluoromethylation based on radical intermediates, as a valuable alternative transformation using the inexpensive and stable solid sodium trifluoromethanesulfinate (CF3SO2Na; Langlois’ reagent), has attracted much attention and has become a hot research field. This review examines recent advances in radical trifluoromethylation reactions with CF3SO2Na as CF3 source.
