No transition metal! Fluorinated hypervalent‐iodine reagents react with TEMPONa in the presence of an alkene under mild conditions to give the corresponding perfluoroalkylaminoxylation products. These radical addition/trapping reactions occur with high stereoselectivity using commercially available reagents, and the product alkoxyamines are readily transformed into the corresponding alcohols.

CF3-addition product formed, which is readily determined by 19F-NMR spectroscopy, rateconstants for trifluoromethyl radicaladdition to the π-acceptor can be calculated. The practical method is also applicable to measure rateconstants for the addition of other perfluoroalkyl radicals to alkenes as documented for CF3CF2-radical addition reactions.
