Introduction of the trifluoromethyl (CF3) group into organic compounds has garnered substantial interest because of its significant role in pharmaceuticals and agrochemicals. Here, we report a hydroxylamine‐mediated radical process for C(sp2)−H trifluoromethylation of terminal alkenes. The reaction shows good reactivity, impressive E/Z selectivity (up to > 20:1), and broad functional group compatibility. Expansion of this approach to perfluoroalkylation and late‐stage trifluoromethylation of bioactive molecules demonstrates its promising application potential. Mechanistic studies suggest that the reaction follows a radical addition and subsequent elimination pathway.
