Olefin halofluorination involves the in situ generation of a halogen-fluoride reagent and subsequent addition to an olefin. The characteristics of this reaction were investigated with three model olefins (allylbenzene, 1-hexene and propene) in order to assess its potential for labeling molecules with the positron-emitting radionuclide fluorine-18 at the no-carrier-added level. The most favorable conditions for bromofluorination utilized 1, 3-dibromo-5, 5-dimethyl-hydantoin, with dichloromethane as solvent. Halofluorination proceeds rapidly and efficiently using either equivalent or substoichiometric quantities of fluoride ion; HF/pyridine or metal fluorides with acid can be used, and up to three equivalents of water can be present. By this reaction, allylbenzene was labeled with fluorine-18 in 32% yield, under either carrier-added or no-carrier-added conditions. Thus, we anticipate that this reaction will prove very useful in the labeling of other molecules with fluorine-18.
