the precursor and other reagents, as well as the limited availability of parent 18F sources of suitable reactivity ([18F]F– and [18F]F2). There is a high-priority demand for general methods allowing access to [18F]CF3-substituted molecules for application in pharmaceutical discovery programmes. We report the development of a process for the late-stage [18F]trifluoromethylation of (hetero)arenes from

Herein, we describe a valuable method for the introduction of the [18F]CF3 group into arenes with highly improved specific activity by the reaction of [18F]trifluoromethane with aryliodides or aryl boronic acids. This [18F]trifluoromethylation reaction is the first to be described in which the [18F]CF3 products are generated in actual trace amounts and can therefore effectively be used as PET tracers

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

The present invention relates to a process for producing an organic compound comprising an 18F atom, which process comprises treating a precursor organic compound comprising a –CY2X group with: (i) [18F] fluoride; and (ii) an activator which comprises a compound comprising silver, gold, copper or platinum, or which comprises elemental silver, gold, copper or platinum wherein: X is a leaving group; and each Y is independently selected from F, Cl, Br and H. Also described is the use of an activator which comprises a compound comprising silver, gold, copper or platinum, or which comprises elemental silver, gold, copper or platinum, in a process for producing an organic compound comprising an F atom according to the invention. A kit, composition and compound are also described.
