A new electrophilic difluoromethylating reagent has been developed. The S-(difluoromethyl)diarylsulfonium tetrafluoroborate has been shown to be effective for the introduction of an electrophilic difluoromethyl group into the following nucleophiles: sulfonic acids, tertiary amines, imidazole derivatives, and phosphines. The reagent failed to transfer the difluoromethyl group to phenols, carbon nucleophiles

The present invention relates to compositions and methods for the synthesis of
18
F labeled compounds. In particular, the present invention relates to a copper (I) mediated one pot method for
18
F-trifluoromethylation of aromatic- or heteroaromatic halides with difluoro(iodo)methane (e.g., for use at PET imaging agents).

report is concerned with an efficient, Cu(I)-mediated method for the radiosynthesis of [(18)F]trifluoromethyl arenes, abundant motifs in small molecule drug candidates and potential radiotracers for positron emission tomography. Three (18)F-labelled radiotracer candidates were synthesised from [(18)F]fluoride ions as proof of principle. The new protocol is widely applicable for the synthesis of novel
