Positronemissiontomography has emerged as the leading method for medical imaging with fluorine‐18 as the most widely used radioactive isotope. Here we report a semi‐automated method for the preparation of valuable [18F]trifluoromethylcopper, as well as its use for the radiosynthesis of [18F]trifluoromethylarenes and heteroarenes. Mild conditions of [18F]trifluoromethylation make this method particularly

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 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
