A method for the addition of fluorinated groups to nitrones using an iridium photocatalyst and ascorbic acid as a stoichiometric reducing agent is described. The reaction proceeds through the generation of fluorinated radicals by single-electron reduction of fluorinated alkyl iodides with an iridium complex mediated by visible light. Besides perfluorinated reagents, partially fluorinated alkyl iodides
